¿Quieres que tus alumnos se diviertan con las matemáticas pero no les gusta el cálculo? ¿Quieres repasar las operaciones con tus hijos pero ellos se aburren de hacer siempre lo mismo? ¿Quieres simplemente dejar alucinados a tus amigos con unos cuantos trucos de magia infalibles? Pues presta atención, porque esto te va a gustar.
Averiguar el día de la semana de tu nacimiento.
Seguro que te han contado cosas del día en el que naciste, pero tal vez no sepas qué día de la semana era. No es difícil averiguarlo, aunque debes tener en cuenta que febrero es un mes especial y su número de días varía cada año.
Febrero suele tener 28 días, pero si el año es bisiesto tiene 29. Para saber si un año es bisiesto lo dividimos entre 4 y si la división es exacta, entonces es bisiesto, pero si acaba en dos ceros, también tiene que ser exacta su división entre 400.
Para hallar qué día de la semana fue el 6 de febrero de 2004:
Calcula los días que han pasado desde el comienzo del año: 37 días (31 + 6).
Resta 1 al año de la fecha, divide entre 4 y anota el cociente:
2.004 – 1 = 2.003 y 2.003 : 4 Cociente: 500.
Suma al año de la fecha los días que han pasado del año y el cociente anterior:
2.004 + 37 + 500 = 2.541
Divide el resultado entre 7 y busca el resto en esta tabla:
2.541 : 7 -> Cociente: 363 y resto 0.
- Como el resto es 0, el 6 de febrero de 2004 fue viernes.
Truco para averiguar la fecha de nacimiento.
Dile a la persona que participe en tu juego que:
escriba el número del día de nacimiento; 29 (es el día en que yo nací)
que lo multiplique por 100: 29 x 100 = 2.900
que le sume el mes en que nació: 2.900 + 3 (es el mes en que yo nací) = 2.903
que lo vuelva a multiplicar por 100: 2.903 x 100 = 290.300
y ahora que sume las dos últimas cifras del año de nacimiento: 290.300 + 89 (nací en 1989) = 290.389.
que lo multiplique por 10: 290.389 x 10 = 2.903.890
que le sume el año del descubrimiento de América: 2.903.890 + 1.492 = 2.905.382
y que lo divida entre 2: 2.905.382 : 2 = 1.452.691
Después de esto, pídele el resultado. Resta al número que te haya dado 746 y divídelo entre 5.
1.452.691 – 746 = 1.451.945
1.451.945 : 5 = 290.389
Si el resultado es par como el que nos ha dado a nosotros, las dos primeras cifras serán el día de nacimiento (29), las dos siguientes el mes (03) y las dos últimas el año (89). Si el resultado es impar, la primera cifra será el día de nacimiento, las dos siguientes el mes, y las dos siguientes el año.

I don’t know who you wrote this for but you helped a brother out.
Love it! Reminds me of you, me, Nelson, and Sonny trash talking each other while playing our four player game a while back! Rematch, anyone?? 😉
wow. where do they GET this stuff…My husband and I make this face we JOKINGLY call the “probable serial killer face” when the kids do something freaky like that…you know, like accuse inanimate objects of ordering them to do stuff?so very The Shining of them, isnt it?
Thanks for posting this and reminding everyone that there IS great stuff happening out there! I love that double EBT money program — RI had it for a while as well, and I think it’s really invaluable.
I noticed last summer walking around Atlanta that the city had installed “Stop” for pedestrian signs in the crosswalks, with a little stop sign rather than yield sign. I also know from the experience of my family members down there that there was increased enforcement of the yield to pedestrian law, in fact my brother got a stiff ticket for it. From my experience of walking several miles around the city of Atlanta, pretty much the paragon of American sprawl, I’d say the signs and enforcement had an effect. I was amazed at how often cars yielded to me in crosswalks.

Maybe Lamar was given Kobe’s 3pt workout that Trevor left when he went to Houston Lineups are lineups and although giddy, I won’t admit it until I see them play. I’ve been disappointed by so many theoretically awesome lineups that it’s just natural for me to be a bit reserved.One thing I think that may be granted this season is a full, growing Bynum. If he can play defense like Pau did (wow, did I actually type that?) I won’t care if Ron has lost a step or two.… but i do wish that he won’t lose his mind.
This awesome blog is obviously educating as well as diverting. I have picked up a bunch of useful advices out of this amazing blog. I’d love to return every once in a while. Thanks!
Lovely sandals. I’m afraid I’m a flip-flop-aholic. I live in them from May through to October, unless the weather is horrible. I have around 10 pairs in various colours and with various beading, sequins, patterns, etc.Hope your daughter has had a fabulous time. x
The next stage is epidemics. That's being reported now, but of course this is the white media and they're devils, so don't trust them when they talk about infections started to take hold. Can't be true.In any case, I'm sure the Africans who are rushing aid to Haiti have this under control. No room for the United States. Damn the white devils and their white devil water, food, and medicine. Plagues on the earth, they are.
I can’t hear anything over the sound of how awesome this article is.
Bloom, vos commentaires sur la pointe ardennaise m’intéressent toujours. C’est un endroit que je connais bien et que j’ai aimé avec passion, (il faut dire : « j’ai aimé, c’est un effet du temps), notamment le village dont vous parlez, mais je l’ai abordé dans de toutes autres conditions. Il y a longtemps. Je ne sais pas ce que j’en penserais aujourd’hui.
Trust is relative. Sometimes there is an open arrangement, so no one really has to feel violated if an affair happens. If that’s the case, then why would it be difficult to keep the relationship going? On the other hand, if one person wants monogamy and the other doesn’t, then that would be a problem. Best to know the other’s point of view before starting something that may lead to an ongoing thing. Some people just get bored and want sex. Thats ok, if it ok with all concerned.
Big help, big help. And superlative news of course.

I’m planning to do just the opposite. Once the prices come down, I’m looking to buy somewhere more in the country east of the metro. The trick will be finding a place that will still allow me a modest commute to the ‘burbs for work. I’m sure there would be perks livng downtown, but I’d rather have space and quiet. I lived in apartments for 12 years. I’d rather not buy one. – Rate this comment: 0 0
Hiya, I am really glad I have found this information. Today bloggers publish just about gossips and internet and this is actually frustrating. A good site with interesting content, that’s what I need. Thank you for keeping this web site, I’ll be visiting it. Do you do newsletters? Cant find it.
This article keeps it real, no doubt.
Love, love, love your blog! I just bought a house in the Atlanta area and am always looking for ideas! Once I find a piece of furniture for my office/yoga room I would love to see how you could make it pretty!!
Flotte tur bilder på himmelsk,om veret ikke er så bra så er det godt med ein fjelltur.Her skinner sola ,det har den gjort heile uka,men det er kald vind,i dag er det mildere skulle vert ute i hagen ,men kroppen vil ikke fungere heilt i dag.Ønsker deg en fin helg :=)
You’ve captured this perfectly. Thanks for taking the time!
Just what the doctor ordered, thankity you!
Hi Kelly, your message just popped up now so sorry for the late response. I agree, I like real deal bad girls rather than maligned heroines, although that can work very well too. I hope you enjoy Zoe’s story!
Zostają po nas pomniki póki jeszcze jest ktoś, kto nas odwiedza, a za 100 lat leżeć będzie tu ktoś inny. Taka kolej, święto zmarłych napawa mnie refleksją nad teraźniejszością, która za szybko umyka.
Hello Sarah,I made your lentil salad last week and it was just great!In general, I love mixing ingredients that might at first sight seem a little exotic together, that´s why this salad absolutely suits my taste. I hadn´t thought that all the spices in the dressing work soo well together.And congratulations to your great blog, I will get further inspiration here (and information).Best regards,Sarah
I visited my local Radio Shack store today with intent to buy two Blackout Buddies to get the third BB free. However, RS wouldn’t honor this promotion as it’s been advertised in your video; the store will not provide a free BB unless I purchase one of the ARC radios. Also, when I attempt to purchase three BB from the RS website, there is no mention of a ‘buy 2, get 1 free’ offer during checkout.
Keep these articles coming as they’ve opened many new doors for me.
Glosslizard,You have my lemming blush, Orchid Rose! I am so lusting for it. I own a fan brush too (by Shu) but quite haven’t figured out what to do with it. Maybe I’ll give it a go with some of my brighter, highly pigmented (aka scary) blushes!
Wow, amazing blog structure! How long have you been running a blog for? you made blogging glance easy. The overall look of your web site is wonderful, let alone the content material!
Ordered another product from Benedict.It took awhile but it came, I trust this guy on all my purchases.So dont hesitate to get some stuff from Benedict, you can trust him.Thanks Benedict,till the next transactionMike
Thanks for taking the time to post. It’s lifted the level of debate
I know exactly what Maddie is going to do. Run away crying, fall into the arms of the first guy she sees (presumably an attractive bald man from Chicago who’s a big fan of Brooke), and the two fall instantly in love – and make with the whoopie right there in the hallway!I just wrote your next 3 pages, buddy.
Super portrait, en plus de voyager dans l’espace et dans le temps, cet article met l’eau à la bouche, le monde ou Le Monde, la « bouffe » s’infiltre partout et c’est tant mieux!
The answer of an expert. Good to hear from you.
Por favor me informem como devo tirar pela internet a 2ª via di cartão cujo vencimento é 12.02.2010, nº do cartão 5184916647293640, estou tentando já faz algumas hora e não estou conseguindo.Muito obrigada,Marileide
Ah, i see. Well that’s not too tricky at all!”
This piece was cogent, well-written, and pithy.
the problem is…there are many people I know who would prefer to cross a road running in front of the fast paced traffic than use an overbridge or subway because they do not want to climb up and down the stairs as it eats up too much of their time..
Surprisingly well-written and informative for a free online article.
Just the type of insight we need to fire up the debate.
Intelligence and simplicity – easy to understand how you think.

You probably misunderstood what I was asking. Of course everything is designed, because it was chosen to be one way or another. My question was why one company decided to make a set of choices and designs in one way for one game and make another set of choices and designs in another way for another; others have put some light to the answer.
Poate nu ti-ai dat seama dar telefonul din stanga era cu WP7, penibil pe langa cel din dreapta cu iOS 5 Apple. Rad si acum, ‘teen anal’ in loc de ‘ten am’. Minunat, in conditiile in care Microsoft a atacat Apple ca Siri e o chestie pe care ei o au deja de un an.

cool – I too have many M&S tins from this year (Christmas & custard cream) which hold my crafting tools.If you're interested on my blog I've got a post about 10% off at funkyhoney.co.uk. x
That’s really thinking at an impressive level
I don’t even know what to say, this made things so much easier!
Hy,thank you for the fast answer! I think I will go with the X230 because as a student you get it cheaper and I have a comfortable docking station to connect everything easily.Do you know another good notebook with an IPS Panel and a higher resolution than 1366 x 768 with a 12″ till 14″ display?best regards and have a nice weekend!

The honesty of your posting shines through
Es muy útil vuestra ayuda, pero aún tengo dudas porque no sabemos qué pack coger, quiero una web sencilla pero profesional a la vez y no me gustarÃa tener lÃmites en cuanto a textos, fotos, vÃdeos o u otros complementos de la web, como pueden ser entradas animadas, o fondos en movimiento y cosas asÃ. No sé si me explico; igualmente me ha sido de gran ayuda vuestra respuesta, empezaremos cuanto antes con 1&1 y ya me pasaré por aquà a contaros que tal nos va gracias.un saludo.
