Question

If + = x, - = +, x = ÷; then 10 + 2 - 4 × 2 = ?

• A. 10
• B. 19
• C. 22
• D. 24

Answer 1

Answer:

C. 22

Given the symbol changes:

• (+) means (\times)

• (-) means (+)

• (\times) means (\div)

So,

$10 + 2 - 4 \times 2$

becomes

$10 \times 2 + 4 \div 2$

Now apply BODMAS:

$10 \times 2 = 20$
$4 \div 2 = 2$
$20 + 2 = 22$

Therefore,

$\boxed{22}$
