The Step-by-Step Solution
Let's solve the equation carefully using the order of operations:
7\times7-7\div7+7
Step 1: Multiplication and Division First
Calculate the multiplication:
7 × 7 = 49
Calculate the division:
7 ÷ 7 = 1
The equation now becomes:
49 − 1 + 7
Step 2: Work Left to Right
Now perform subtraction first:
49 − 1 = 48
Then addition:
48 + 7 = 55
Final Answer
✅ 55
Why Many People Get It Wrong
A common mistake is to solve the equation from left to right without respecting the order of operations, or to perform the subtraction before the division. This leads to incorrect answers.
The golden rule is simple:
Multiplication and division come before addition and subtraction.
When operations share the same priority level, work from left to right.
