evaluate n+(-12) for each value of n. n=15
plug in n for 15
15+(-12)
which is the same thing as:
15-12 = ?
To evaluate the expression n + (-12) for a given value of n, simply substitute the value of n into the expression and perform the addition.
In this case, the given value of n is 15. So, we substitute 15 into the expression:
15 + (-12)
To add a positive number and a negative number, we subtract the absolute value of the negative number from the positive number:
15 - 12
Performing the subtraction:
15 - 12 = 3
Therefore, when n is equal to 15, the value of n + (-12) is 3.
