What is the value of the expression: 7 x 8 - 10?

• A. 46
• B. 54
• C. 48
• D. 50

Answer: (A)

To solve the expression \( 7 \times 8 - 10 \), you must first calculate the multiplication before performing the subtraction, following the order of operations (often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). First, compute \( 7 \times 8 \): \[ 7 \times 8 = 56 \] Next, subtract 10 from this product: \[ 56 - 10 = 46 \] Thus, the value of the expression \( 7 \times 8 - 10 \) is 46. This is why the correct answer reflects that value. The calculations adhere to standard arithmetic procedures, leading to the result being derived accurately.

First, compute ( 7 \times 8 ):

[

7 \times 8 = 56

]

Next, subtract 10 from this product:

[

56 - 10 = 46

]

Thus, the value of the expression ( 7 \times 8 - 10 ) is 46. This is why the correct answer reflects that value. The calculations adhere to standard arithmetic procedures, leading to the result being derived accurately.
