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
