Sorry but the FRACTION is the primary function of this equation - not division or multiplication.

That is what I was attempting to explain.

This converts to this in simple math/algebra (482)(9+3)= x ...and that is not the way the origninal equation is written.

Given the equation 482Χ12 how would you solve it?

Algebra equation it becomes 48/2x12. You have to account there is no division symbol - only fractions.

Just work simply from left to right.

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

-3274701-2.png
-3274701-3.png

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.

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.
48ΧΧ12 <-- 48Χ=482
(48)()(12)
(12)(48)() <-commutative property


Everything leads to 288

48 / 2 (9 + 3):

1. Parentheses: (9 + 3) = 12.
2. Exponents: none. (Actually there are: (48^1) / (2^1)((9^1) + (3^1)), but we can ignore them)
3. Multiplication: 2 * 12.
4. Division: 48 / 24 = 2.


Edit: Wow, only 63.89% of the respondents have answered this correctly?

Why are you giving multiplication precedence over division if they're the only two operands left after the parenthesis?

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.

Whatever the answer the question started quite a debate and I got lost after the question so bye bye.

Wow. Don't overthink it folks. Go back to simple math.

482(9+3) Once you do the work in brakets this question becomes
482x12 At this point you follow the math rule that you do complex problems in the order they appear, which gives you
24x12= 288
