# Understanding Negative Numbers, Integers, and Positive Numbers Primary 5 Mathematics

### Negative Numbers

**Definition**: Negative numbers are numbers less than zero.**Example**: -1, -5, -10**Uses**: They show temperatures below zero or debts (money owed).**Visual**: Think of a number line with zero in the middle. Negative numbers are on the left side of zero.- For example, -3 means 3 steps to the left of 0.

### 2. Integers

**Definition**: Integers are all whole numbers. This includes negative numbers, zero, and positive numbers.**Example**: -3, -2, -1, 0, 1, 2, 3**Tip**: If you can write the number without a fraction or decimal, it is an integer.**Visual**: On a number line, integers are all the dots you see, both on the left and right of zero.

### 3. Positive Numbers

**Definition**: Positive numbers are numbers greater than zero.**Example**: 1, 5, 10**Uses**: They show quantities you have, like 5 apples or 10 pencils.**Visual**: On a number line, positive numbers are on the right side of zero.- For example, +4 means 4 steps to the right of 0.

### Summary

**Negative Numbers**: Left of zero (e.g., -4).**Integers**: All whole numbers (e.g., -2, 0, 3).**Positive Numbers**: Right of zero (e.g., +7).

Remember, the number line helps you see where numbers belong! 🟢
