The Step-by-Step Solution
Let’s break down the equation using the proper order of operations:
Step 1: Multiplication and Division (Left to Right)
First, we tackle the multiplication on the far left:
7 × 7 = 49
Next, we handle the division:
7 ÷ 7 = 1
Now, substitute those results back into the equation. It now looks like this:
49 - 1 + 7
Step 2: Addition and Subtraction (Left to Right)
Many people make the mistake of adding the 1 and 7 together first because "addition comes before subtraction" in the acronym. However, they are on the same tier, so we must go left to right.
First, the subtraction:
49 - 1 = 48
Finally, the addition:
48 + 7 = 55
The Final Answer
The correct answer is 55.
