NOW, we have the issue of, "What if you interpret this as a fraction?" Above, HoldenMichael writes 48/2, and that makes sense.... but the real problem is that Holden forgets to write the rest of the problem in the denominator. There is nothing that separates the (9+3) from being in the denominator along with the 2. So in reality, if one would look at the ÷ as a / sign, the problem would look like this:
I didn't forget to write "2(9+3)" as a whole denominator because it wasn't written as a whole denominator.
If someone wanted to make it the whole denominator, they'd have to include the brackets. We don't need to guess the intention because it's math.
The symbol for division is not used interchangeably with "/" to mean fraction. It's used only to symbolize division.
If they want to have us view "2(9+3)" as a whole denominator when using "/" as a symbol for fraction, then they have to use brackets. Otherwise, it's a fraction being multiplied with a sum.
