Question

Evaluate. 90 • 4 – 14 ÷ 2 + 10² ÷ 5 • 2

Answer 1

90 x 4 - 14 / 2 + 10^2 / 5 x 2
For this expression, you would use the method PEMDAS.
(Parentheses Exponents Multiplication Division Addition Subtraction)
The first one available in this expression is Exponents (10^2=100)
90 x 4 - 14 / 2 + 100 / 5 x 2
Then Multiplication (90 x 4 = 360 and 5 x 2= 10)
360 - 14 / 2 + 100 / 10
Next is Division (14 / 2 = 7 and 100 / 10 = 10)
360 - 7 + 10
Now Addition or Subtraction (whichever one is first from left to right)
353 + 10
90 x 4 - 14 / 2 + 10^2 / 5 x 2 = 363
