+590 So we have the equation 60/5(7-5).
First simplify the '7-5' in the brackets to get 60/5(2)
Simplify again and get 60/10
And that's just dividing 60 by 10, so the answer is 6.
6 is our answer.
Not 24.
New update: I think this answer is wrong. Look at Alan's answer. Sorry. 
Yeah. I kept arguing they have to deal with the Parantheses first, PEMDAS, and all, but their logic got them to 60/5*(2) so then they followed that with 12*2 = 24. I kept telling them there was no "*" sign so they had to multiply first because they still have to deal with parantheses first, but alas, they didn't believe me.
+33615 No Gh0sty!
Parentheses first: 60/5*2
Divide and Multiply have the same precedence so you work from left to right:
60/5*2 → 12*2 → 24
If you legit put the equation into a real life TI-84 calculator as "60/5(7-5)" you'll get 6. The scientific calculator on the computer is incompatible with that equation because it forces you to place the multiplication symbol in between the 5 and the (.
What you're saying here is that the equation is 60 over 5 THEN multiply by 2 instead of 60 over 5(2)
It doesn't say that there's a multiplication sign in the middle of 5 and (7-2). Adding a sign there would make the equation different. It would be regrouped into:
60 ÷ 5 × ( 7 - 5 ) = ( 60 ÷ 5 ) ( 7 - 5 )
Which is different from the original equation.
But if no multiplication sign was added, it would be purely '60 divided by the product of 5 and 7 minus 2' which is 6.
60 ÷ 5 ( 7 - 2 )
60 ÷ 5 ( 2 )
60 ÷ 10
6
Remember that the term 5(7-5) is a monomial term that has been simplified from (35-25) and that you need to DISTRIBUTE the 5 back into the brackets to solve the brackets.
It says
60 ÷ 5 ( 7 - 2 )
60 ÷ 5 ( 2 )
60 ÷ 10
6
But that's a typo. Meant
60 ÷ 5 ( 7 - 5 )
60 ÷ 5 ( 2 )
60 ÷ 10
6
Was thinking ahead to the answer.
+590 Oops. Sorry Alan. Sorry. I'll delete my answer. Sorry guest.
What's wrong with me these days?
+590 No wait. I'll leave my answer. People can learn by my mistake too.
Always think positively.
+33615 There is nothing in the original expression to indicate that 5(7-5) has been factored from (35 - 25). If it had been the correct way to express the result would have been 60/(5(7 - 5))
60/5(7 - 5) has an implied multiplication so should be read as 60/5*(7-5)
To avoid ambiguity either use parentheses or write as \(\frac{60}{5}(7-5)\text{ or}\frac{60}{5(7-5)}\) as appropriate.
