The correct Answer is:
To solve the expression \( 7 + 7 \div 7 \times 7 \), we will follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). This is often abbreviated as PEMDAS. ### Step-by-Step Solution: 1. **Identify the expression**: \[ 7 + 7 \div 7 \times 7 \] 2. **Perform division first**: \[ 7 \div 7 = 1 \] Now substitute this back into the expression: \[ 7 + 1 \times 7 \] 3. **Next, perform multiplication**: \[ 1 \times 7 = 7 \] Substitute this back into the expression: \[ 7 + 7 \] 4. **Finally, perform addition**: \[ 7 + 7 = 14 \] Thus, the simplified result of the expression \( 7 + 7 \div 7 \times 7 \) is: \[ \boxed{14} \]
