Ferdinand Porsche Posted May 7, 2012 Posted May 7, 2012 I am working full time on my math, I have after some time realized that engineering is what I want to do. Therefore I need to do great things to my math and physics skills! As of today I work to go from complete noob to pro... Sometimes I just can't manage to understand a simple task Todays question is how come 6-(-5)x2+(-3)x5 is 1? (sorry, I just don't get this one. I end up at negative numbers or numbers which is larger than the number one)

sri_nav Posted May 15, 2012 Posted May 15, 2012 (edited) 6 - ( (-5)x2 ) + ( (-3)x5 ). dis is how it is calculated Edited May 15, 2012 by sri_nav

You first do the Bracket operation, then Division(although, we don't need it here), multiplication, addition and finally, subtraction [bODMAS rule]. That must work. This one should be solved by enclosing bracket to the pair of numbers undergoing multiplication. And then, some IQ of yours would do good. Edited June 16, 2012 by space stuff
