If you can't answer that yourself, you need to spend less time on the internet and more time in your studies.
The actual answer is 32. It appears a lot of the answerers need to spend more time in their studies, too. Multiplication has the highest precedence in that equation.

You would have to do the multiplication first...
5+9-4+15+7=32

Without parenthesis marks, people will come up with different answers. I believe in this case, one must first do the multiplication. So, the equation is now, 5+9-4+15+7. This yields 14-4+15+7 = 25 + 7 = 32.

The order that you work the operators (+ - / X ) is:
1. Parentheses
2. Exponents (and roots)
3. Multiplication and Division
4. Addition and Subtraction
Keeping this in mind, we can rewrite the equation as:
5 + 9 - 4 + (5 x 3) + 7
once you do the 5 X 3 part (which equals 15)
the equation looks like this
5 + 9 - 4 + 15 + 7
Since NOW the operators are just + and - you can do them in any order you want to.
By the way it is ok to put in the parentheses to help you work it out. Mathematicians do it all the time.
A mnemonic to use to remember the order is PEMDAS or "Please excuse my dear Aunt Sally"

the unusual function is a x b = c and a + b = c it extremely is, a million.5 x 3 = 4.5 and a million.5 + 3 = 4.5 a million.2 x 6 = 7.2 and a million.2 + 6 = 7.2 if a is any selection then pick b = a/(a - a million) if a > a million or b = a/ (a million- a) if a < a million. on your question pick a = 3 then b = a million.5 pick a = 6 then b = a million.2 further pick distinctive values for a to get the record of those numbers.
