That is what I was attempting to explain. This converts to this in simple math/algebra (48÷2)(9+3)= x ...and that is not the way the origninal equation is written. My System Specs

 13 May 2011 #73 Hopalong X Windows7 Pro 64bit SP-1; Windows XP Pro 32bit 6,472 posts Grafton,IL Algebra equation it becomes 48/2x12. You have to account there is no division symbol - only fractions. My System Specs

Just work simply from left to right.    Quote: Originally Posted by Hopalong X Sorry but the FRACTION is the primary function of this equation - not division or multiplication.

And the notation you used isn't how the equation is written, because as I said, you're giving multiplication precedence over division, which results in the equation being written as 48/(2(9+3)). ÷ and / both simply mean divide, too. Doesn't change anything. The expression is computed as The main problem with it though is just how different people follow different standards. It is an ambiguous equation, because the way it's written should be avoided, and should be written as you said (48/2)(9+3) to make it crystal clear. My System Specs

Well, that answers everything, right? *Just a thought, would it make more sense if it were converted to have the same operator altogether? e.g. 48Χ½Χ12 <-- 48Χ½=48÷2 (48)(½)(12) (12)(48)(½) <-commutative property Everything leads to 288 My System Specs

Ah, correct that when they are the remaining explicit operators, they are performed left to right. I was thinking 48 / 2(12), while typing 48 / 2 * 12.

 13 May 2011 #80 alfred01 Windows 7 Home Premium 64 bit SP1 1,606 posts Toronto Wow. Don't overthink it folks. Go back to simple math. 48÷2(9+3) Once you do the work in brakets this question becomes 48÷2x12 At this point you follow the math rule that you do complex problems in the order they appear, which gives you 24x12= 288 My System Specs
