1. Let's start by understanding the problem: you want to learn about division and multiplication. 2. Multiplication is the process of adding a number to itself a certain number of times. The formula is $a \times b$, which means adding $a$ to itself $b$ times. 3. Division is splitting a number into equal parts. The formula is $\frac{a}{b}$, which means dividing $a$ into $b$ equal parts. 4. Important rules: - Multiplying any number by 1 gives the same number. - Multiplying by 0 gives 0. - Division by zero is undefined. 5. Example of multiplication: $3 \times 4 = 3 + 3 + 3 + 3 = 12$. 6. Example of division: $12 \div 4 = \frac{12}{4} = 3$ because 12 split into 4 equal parts is 3 each. 7. Practice these operations with simple numbers to get comfortable.
