Practice makes perfect

To determine this product, we will follow the order of operations. Note that in this case, there are no parentheses surrounding the negative. - 5^2 ⇔ -1 ( 5^2 ) This means that we should evaluate as though parentheses surround the exponent and multiply the result by -1.

-1 ( 5^2 )
-1 (25)
