Question

8(6+5) - 10 = ?

• A. 76
• B. 78
• C. 80
• D. 82

Hint:

Always follow the order of operations (PEMDAS/BODMAS) when solving mathematical expressions to avoid mistakes.

Answer 1

The Correct Option is B

To solve this expression, we must 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 commonly known as PEMDAS or BODMAS. 
Step 1: First, solve the expression inside the parentheses: \[ 6 + 5 = 11 \] 
Step 2: Now, multiply the result by 8: \[ 8 \times 11 = 88 \] 
Step 3: Finally, subtract 10: \[ 88 - 10 = 78 \] Therefore, the correct answer is 78.
