In a coded arithmetic system, the symbol '+' actually means subtraction and the symbol '-' actually means multiplication. Using these substitutions, what is the value of: $12 + 4 - 3$?

1. 5
2. 0
3. 1
4. 3

Correct answer: 0

Solution

Here, '+' means subtraction and '-' means multiplication. So the expression becomes $12 - 4 \times 3$. Using BODMAS, $4 \times 3 = 12$, and then $12 - 12 = 0$.
