subtraction is addition of a negative. people! 11 x 2 + 32 - 21 + 5 x 3 + 5 x 1 (11 x 2) + 32 - 21 + (5 x 3) + (5 x 1) 22 + 32 - 21 + 15 + 5 22 + 32 + (-21) + 15 + 5 (The brackets aren't for BODMAS, they're for representation of a negative integer) 54 + (-21) + 20 Either way you go about that, you get 53: 54 + (-21 + 20 = -1) = 53 (54 - 21 = 33) + 20 = 53 (54 + 20) - 21 or (54 + 20) + (-21) = 74 - 21 or 74 + (-21) = 53 Interesting how you got 13, had me for a while there had to do it on my own. Reminds me of those times when you tried to solve the problem in a Math paper and your answer wasn't one of the choices. SO FRUSTRATING :-/ Then you'd raise your hand and tell the teacher that the question is wrong and he'd say there's nothing wrong with it, and then you'd already know that 13 is not the answer... but where to from here!? Hahaha... Thank you for bringing this up @Claire. On Mon, Jan 3, 2011 at 12:03 PM, Lenchipai Nakodony <lenchi@inbox.com>wrote:
What KTN was asking for was you ADD ALL THE NUMBERS ON THE BOARD (it was was something like a brain teaser). You add them all up and you will get the 120.
Good day
