1. The problem is to understand and apply the MDAS rule in arithmetic operations. 2. MDAS stands for Multiplication, Division, Addition, and Subtraction, which is a mnemonic to remember the order of operations. 3. The order of operations is: first do Multiplication and Division from left to right, then do Addition and Subtraction from left to right. 4. This means if you have an expression like $6 + 3 \times 2$, you first multiply $3 \times 2 = 6$, then add $6 + 6 = 12$. 5. If the expression is $12 \div 4 + 2$, you first divide $12 \div 4 = 3$, then add $3 + 2 = 5$. 6. Remember that multiplication and division have the same priority and are done from left to right. 7. Similarly, addition and subtraction have the same priority and are done from left to right. 8. Parentheses can override this order, but since MDAS does not include parentheses explicitly, we follow the above rules. Final answer: MDAS means perform Multiplication and Division first (left to right), then Addition and Subtraction (left to right).
