What is 90 + 90 ÷ 90 + 90 × 90 Equal To? Answer Explained
What is the correct answer for the expression 90 + 90 / 90 + 90 × 90?
90 + 90 ÷ 90 + 90 * 90 = 8191 (answer)
Whenever you are dealing with any mathematical operation just remember “PEDMAS” and proceed accordingly.
P - Parenthesis
E - Exponents
D - Division
M - Multiplication
A - Addition
S - Subtraction
PEDMAS means that we first evaluate parentheses/brackets, then evaluate exponents/orders, then evaluate multiplication-division, and finally evaluate addition-subtraction.
We want to solve this expression 90 + 90 ÷ 90 + 90 × 90 - 90.
The expression above has no parentheses or exponents, so we evaluate multiplication-division then addition-subtraction.
90 + 90 ÷ 90 + 90 × 90 = ?
Step 1 - evaluate the division 90 ÷ 90 = 1 to get
90 + 1 + 90 × 90
Step 2 - evaluate the multiplication 90 × 90 = 8100 to get
90 + 1 + 8100
Step 3 - evaluate the addition 90 + 1 = 91 to get
91 + 8100
Step 4 - evaluate the addition 91 + 8100 = 8191 to get
8191
Thus, the answer is:
90 + 90 / 90 + 90 × 90 = 8191
