What is 21 plus 21 over 21 plus 21 times 21 minus 21 Equal To? Correct Answer Explained

What is the correct answer for the expression 21 + 21 / 21 + 21 × 21 - 21?

21 + 21 ÷ 21 + 21 * 21 - 21 = 442 (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 21 + 21 ÷ 21 + 21 × 21 - 21.

The expression above has no parentheses or exponents, so we evaluate multiplication-division then addition-subtraction.

21 + 21 ÷ 21 + 21 × 21 - 21 = ?

Step 1 - evaluate the division 21 ÷ 21 = 1 to get

21 + 1 + 21 × 21 - 21

Step 2 - evaluate the multiplication 21 × 21 = 441 to get

21 + 1 + 441 - 21

Step 3 - evaluate the addition 21 + 1 = 22 to get

22 + 441 - 21

Step 4 - evaluate the addition 22 + 441 = 463 to get

463 - 21

Step 5 - finally, evaluate the subtraction 463 - 21 = 442 to get

442

Thus, the answer is:

21 + 21 / 21 + 21 × 21 - 21 = 442
