Answer:
0
Step-by-step explanation:
Follow the signs rule:
IF:
There is a + sign, and the number directly next is +, add
There is a + sign, and the number directly next is -, subtract
There is a - sign, and the number directly next is +, subtract
There is a - sign, and the number directly next is -, add
In this case, there is a positive & a negative sign, so the sign is negative. Subtract:
7 + (-7) = 7 - 7 = 0
0 is your answer.
