Question

If + = x, - = +, x = ÷; then 6 + 3 - 2 × 1 = ?

• A. 20
• B. 21
• C. 19
• D. 24

Answer 1

Answer:

A. 20

Given the symbol substitutions:

• + means ×

• - means +

• × means ÷

So the expression

6 + 3 - 2 × 1

becomes

6 × 3 + 2 ÷ 1

Now apply the usual order of operations:

• $(6 \times 3 = 18)$

• $(2 \div 1 = 2)$

Then:

(18 + 2 = 20)

✅ Answer: 20
