What is 20 + 20 ÷ 20 + 20 × 20 Equal To? Answer Explained
What is the correct answer for the expression 20 + 20 / 20 + 20 × 20?
20 + 20 ÷ 20 + 20 * 20 = 421 (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 20 + 20 ÷ 20 + 20 × 20 - 20.
The expression above has no parentheses or exponents, so we evaluate multiplication-division then addition-subtraction.
20 + 20 ÷ 20 + 20 × 20 = ?
Step 1 - evaluate the division 20 ÷ 20 = 1 to get
20 + 1 + 20 × 20
Step 2 - evaluate the multiplication 20 × 20 = 400 to get
20 + 1 + 400
Step 3 - evaluate the addition 20 + 1 = 21 to get
21 + 400
Step 4 - evaluate the addition 21 + 400 = 421 to get
421
Thus, the answer is:
20 + 20 / 20 + 20 × 20 = 421
