Question

If + = x, x=+, -=÷; then 5 + 6 × 2 - 2 = ?

• A. 16
• B. 2
• C. 12
• D. 31

Answer 1

Answer:

D. 31

Given the symbol changes:

• + = ×

• × = +

• − = ÷

Expression:

$5 + 6 \times 2 - 2$

Replace the symbols:

• (+) becomes (×)

• (×) becomes (+)

• (−) becomes (÷)

So the expression becomes:

$5 \times 6 + 2 \div 2$

Using BODMAS:

$5 \times 6 = 30$
$2 \div 2 = 1$

Now:

30 + 1 = 31

Answer: 31
