Question

Use the correct order of operations to solve the expression below.
25 – 3 x (2+1) +9–7

Answer 1

Answer:

18

Step-by-step explanation:

PEMDAS

25-3x(2+1)+9-7

Parentheses first:

2+1=3

Then multiplication

3x3=9

then subtraction

25-9=16

then add

16+9=25

then subtract again

25-7=18

------------------------------------------

Parentheses ALWAYS go first. Multiplication/division can be switched and addition/subtraction can be switched, but it always goes parentheses, then multiplication or division and then addition or subtraction.
