Ferdinand Porsche Posted May 7, 2012 Share 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) Link to comment Share on other sites More sharing options...

sri_nav Posted May 15, 2012 Share Posted May 15, 2012 (edited) 6 - ( (-5)x2 ) + ( (-3)x5 ). dis is how it is calculated Edited May 15, 2012 by sri_nav Link to comment Share on other sites More sharing options...
doG Posted May 15, 2012 Share Posted May 15, 2012 6 - ( (-5)x2 ) + ( (-3)x5 ). dis is how it is calculated From the Homework Help Rules: A simple reminder to all: this is the "Homework Help" forum, not the "Homework Answers" forum.

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.
