What is 7 plus 7 over 7 plus 7 times 7 minus 7 Equal To? Correct Answer Explained
What is the correct answer for the expression 7 + 7 / 7 + 7 × 7 - 7?
7 + 7 ÷ 7 + 7 * 7 - 7 = 50
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 7 + 7 ÷ 7 + 7 × 7 - 7.
The expression above has no parentheses or exponents, so we evaluate multiplication-division then addition-subtraction.
7 + 7 ÷ 7 + 7 × 7 - 7 = ?
Step 1 - evaluate the division 7 ÷ 7 = 1 to get
7 + 1 + 7 × 7 - 7
Step 2 - evaluate the multiplication 7 × 7 = 49 to get,
7 + 1 + 49 - 7
Step 3 - evaluate the addition 7 + 1 = 8 to get,
8 + 49 - 7
Step 4 - evaluate the addition 8 + 49 = 57 to get,
57 - 7
Finally, evaluate the subtraction 57 - 7 = 50 to get
50
Thus, the answer is:
7 + 7 / 7 + 7 × 7 - 7 = 50
