Question

Find the value of the following expression.

$-11-5(8-10)-\frac{1}{2}$ of $40$ .

• A. $-21$
• B. $+20$
• C. $-20$
• D. $21$

Answer 1

Answer: (A)

$-21$

$-11-5(8-10)-\frac{1}{2}$ of $40$

Using BODMAS rule, we will first evaluate the bracket

$-11-5\times (-2)-\frac{1}{2}$ of $40$

Now we will evaluate the multiplication and subtraction

$-11+10-20=-1-20=-21$

Hence, option A is the correct answer.
