Simplify (5 + 1)2 - (11 + 32) + 4.
4vir4ik [10]

Answer:

6

Step-by-step explanation:

The trick here is to know PEMDAS.

PEMDAS stands for: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

This is the order in which you should simplify a problem.

Parentheses:

   (5 + 1)^2 - (11 + 32) + 4

   (6)^2 - (43) + 4

Exponents:

   (6)^2 - (43) + 4

   36 - 34 + 4

We have no multiplication or division, so we can skip those steps.

Addition:

   36 - 34 + 4

   40 - 34

Subtraction:

   40 - 34

   6

So 6 is our answer.
