To simplify the expression \( 7 + 7 \times 7 - 7 \div 7 \), we need to follow the order of operations (PEMDAS/BODMAS):
- Parentheses/Brackets
- Exponents/Orders
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Let's break it down step-by-step:
-
Multiplication and Division first:
- \( 7 \times 7 = 49 \)
- \( 7 \div 7 = 1 \)
So, the expression now looks like: \[ 7 + 49 - 1 \]
-
Addition and Subtraction from left to right:
- \( 7 + 49 = 56 \)
- \( 56 - 1 = 55 \)
Thus, the final result is \( 55 \).
The correct response is: 55
