Hey there! :)
3 - (-2) = ??
Let's keep in mind that a negative times a negative is always a positive!
In addition, let's also remember that parenthesis mean multiplication - so that's how we know that we're multiplying!
So, since a negative times a negative equals a positive, then we know that this question is essentially just asking us what 3 + 2 is!
In case we aren't sure how to do this, let's look at our fingers! We start out with 3 fingers, and add 2 more fingers to it! So, 3 fingers to 2 fingers equals 5 fingers!
Therefore, our answer is 5.
3 -(-2) = 5

For this case we have that each student takes 8 \ frac {3} {4} minutes to perform and play 3 songs. Then, we convert the mixed number to a fraction:

Thus, each student takes
minutes.
If there are 9 students in the recital then we have:
minutes.
Thus, the recital lasts at least 78.75 minutes.
