Default Re: Maths

there are rules for them... like, 9 x 7 = 63

to figure it out, you take 1 from whatever number you are multiplying (7-1 = 6) and then put whatever number on the back to make it 9 again (3). 63.

Do you get me?
9 x 9 = (9-1 = 8, 8 + ? = 9, so 9x9 = 81).


2, 3, 4, 5 are all easy. 6 is ok, because you just work what half 12 times is, plus six if its an odd number. 7 is a little tricky, you have to learn that. 8 is easy, evrey time you go up a 10, you go down a 2, 8, 16, 24, 32, 40 and so on. 9 easy, 10 easy, 11 easy, and 12s are fine till you get up there a bit.

I have no memory at all for numbers, tables, formulae, etc but there is a logical way of getting to most of the answers fast.
