📖 Understanding Multiplication & Division
Multiplication is a quick way to do repeated addition. Instead of adding 5 + 5 + 5 + 5, we write 5 × 4 = 20. We call the numbers factors and the result the product.
Division is splitting a number into equal groups. 20 ÷ 4 = 5 means '20 split into 4 equal groups gives 5 in each group'. The result is called the quotient.
Multiplication and division are inverse operations — they undo each other. If 6 × 7 = 42, then 42 ÷ 7 = 6 and 42 ÷ 6 = 7.
When dividing, if the number doesn't split equally, we get a remainder. 17 ÷ 5 = 3 remainder 2 (because 5×3=15, and 17−15=2).
🔑 Key Points to Remember
- ✓Multiplication: repeated addition (3 × 4 = 3+3+3+3 = 12)
- ✓Division: sharing equally or repeated subtraction
- ✓Multiplication is commutative: 4 × 6 = 6 × 4
- ✓Division is NOT commutative: 12 ÷ 4 ≠ 4 ÷ 12
- ✓Any number × 0 = 0, Any number × 1 = itself
