    freelancedruma, what that u are doing is not first time,and not unique, it is simply (x+1)^2 = x^2+1+2x= x^2+(x+1) +x example 21^2=(20+1)^2 = 20^2 +21+20=441. but you are very genius that you just find it and make really stress on it.

    To REALLY understand why this works: 109^2 = (100+9) x (100+9) = 100^2 + 900 + 900 + 9^2 (by using FOIL) = 10000 + 1800 + 81 = 11881 ie (100+x)^2 = 100^2 + 200x + x^2 Not terribly useful math example, but neat and interesting analogy.

    watch this sweet trick for squaring numbers, idk who came up with it but if no one did before me, then im the first! (credit to whoever did IF its been done before) observe: to find the value of x^2 without a calculator use this method: let x be 23. as long as you know the value of a number^2 previous of x you can use this to find x^2. so - 20^2 = 400. 21^2 = 400 + 20 + 21. 21^2 = 441. 22^2 = 441 + 21 + 22. 22^2 = 484. 23^2 = 484 + 22 + 23. 23^2 = 529

    I paused it to see if I could get it before he told me... :) Got it. But didn't get the "Why does it work"

    If you can recall the pattern in seconds as opposed to the time it would take you to learn it, it would be worth it. If this applied for every 3 digit number that starts with a 1, this would be worth learning. I guess the real point though is that this derives itself from common logic, things that you should learn. Magic doesn't suit well if you have to learn by rote, rote doesn't help anyone. Learning little quirks, and discovery is how you properly learn.

    did he say cube numbers? This looks squared, or did I miss something.

    True but thats because you have been taught maths the 'normal' way. If you learn these patterns, you can apply to all the different sections of math. =)

    Right......I was a bit disapointed.....thought maybe this would be a cool way to teach kids....Sure you can find little patterns like this in things....but if it only works on a certain number of numbers then you come to the point where it becomes unpracticle (You can find such patterns for other numbers...but it would be harder trying to remember all these little patterns & tricks than to just do the math as normal LOL)

    math is fun!

    yeah, math was pretty important because it is universal

    chicken, there is only one pattern this series. There are permutations to the pattern but only one pattern

  • chickenflu4

    when there is an individual pattern for every class of number, it is not a pattern anymore!

    Taoist were scholars. They are very intellectual. I think there was something close to math that they used... but I don't know what. ^^

    what is the connection between taoism and vedic math??

  • tchepi

    for all squared numbers x, consider *only* the last 2 digits dd. There seems to be a pattern for all dd((x+1)^2) - dd(x^2)... (works also when only considering the 2 digits in the middle) Would be interesting to do some tests with a bigger sample of numbers :-)
