The expression $12 - 2 \times 3$ should be solved following the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

1. First, perform the multiplication:
   $2 \times 3 = 6$

2. Then, subtract:
   $12 - 6 = 6$

Thus, the result is $6$.

2. How would you solve $15 + 3 \times 2 - 6$?
3. What happens if you change the expression to $(12 - 2) \times 3$?
4. How does the order of operations affect the outcome of $18 \div 3 + 4$?
5. Can you solve $8 + 2 \times (5 - 3)$?

Tip: Always remember to handle multiplication and division before addition and subtraction when no parentheses are involved!
