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
