### Re: Favorite mental math tricks/shortcuts

On the subject of the number 9, a primary school method of determining if a number is a factor of 9 (and 3 subsequently) is to add up all the digits of the number, they should equal a recognizable multiple of 9: 81 = 8+1 = 9 22221 = 2+2+2+2+1 = 9 954936 = 9+5+4=9+3+6 = 36 This is also recursive(is ...

x = ln(2)?

Since ex is never zero I multiplied through the equation by it, then did the u substitution and solved the quadratic. Double checked on graphing calculator.

Ditto on that. y=ex is the trick.

Start by simplifying [imath]\frac{(2N)!}{(2(N-1))!}[/imath] and [imath]\frac{(N-1)!}{(N+1)!}[/imath]
(N+1)! = (N+1)(N)(N-1)!
(2N)! = (2N)(2N-1)(2N-2)!
and the rest should work itself out.
