Question

(4+6) x 5 - 3 x (2+8) =

• A. 20
• B. 21
• C. 24
• D. 23

Answer 1

Answer:

A. 20

The result of the expression $(4+6) \times 5 - 3 \times (2+8)$ is 20.

Following the BODMAS/PEMDAS rule (Brackets, Orders, Division/Multiplication, Addition/Subtraction), here is the step-by-step breakdown:

1. Solve the Parentheses (Brackets)

First, calculate the values inside both sets of brackets:

• $(4 + 6) = 10$

• $(2 + 8) = 10$

Now, substitute these back into the expression:
$10 \times 5 - 3 \times 10$

2. Perform Multiplication

Next, carry out the multiplication operations from left to right:

• $10 \times 5 = 50$

• $3 \times 10 = 30$

The expression now becomes:
$50 - 30$

3. Perform Subtraction

Finally, subtract the two values:
$50 - 30 = 20$

The final value of the expression is 20.
