we have the expression
24-8:2^2
Remember that
Applying PEMDAS
P ----> Parentheses first
E -----> Exponents (Powers and Square Roots, etc.)
MD ----> Multiplication and Division (left-to-right)
AS ----> Addition and Subtraction (left-to-right)
step 1
solve the exponent first
2^2=4
substitute
24-8:4
step 2
solve the division
8:4=2
substitute
24-2
step 3
solve the subtraction
24-2=22
answer is 22
