Answer:
1
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 plus sign, and a negative sign, therefore, subtract:
5 + (-4) = 5 - 4 = 1
1 is your answer.
