What step would be done
first when evaluating the
numerical expression?
8 + 3 + (7 + 8) + 3

(7+8) because it’s in parentheses PEMDAS

7+8

Step-by-step explanation: Since the value is inside the parenthesis, you solve it first. Using PEMDAS, you see that parenthesis comes first, with P, so you solve that. To help out the full form of PEMDAS is Parnthesis, Exponent, Multiplication, Division, Addition, and Subtraction and that is the order to operations to follow.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
