Evaluate $18 - 3 \times 4 + 24 \div 6$.

हल

1. 01

   Multiplication and division are done before addition and subtraction.

2. 02

   $3 \times 4 = 12$ and $24 \div 6 = 4$, so the expression becomes $18 - 12 + 4$.

3. 03

   Addition and subtraction are then worked from left to right: $18 - 12 = 6$, then $6 + 4 = 10$.
