What Are Whole Integers?
Whole integers include all positive and negative whole numbers, as well as zero.
Examples:
- Positive integers: 1, 2, 3, 10

- Zero: 0
Integers do not include fractions or decimals.
Understanding Adding and Subtracting Integers
When working with integers, the rules depend on the signs of the numbers.
Adding Integers
- Positive + Positive = Add normally
Example: 4 + 3 = 7 - Negative + Negative = Add and keep the negative sign
Example: -4 + (-3) = -7 - Positive + Negative = Subtract and keep the sign of the larger number
Example: 5 + (-2) = 3
Subtracting Integers
Subtracting an integer is the same as adding its opposite.
Example:
- 5 – 3 = 5 + (-3) = 2
- 6 – (-2) = 6 + 2 = 8
Frequently Asked Questions
Q1: How do you add integers with different signs?
Subtract the smaller number from the larger one and keep the sign of the larger number.
Q2: What happens when you subtract a negative number?
It becomes addition. For example, 6 – (-2) = 6 + 2.
Q3: Can integers be decimals?
No, integers are whole numbers only, including negatives and zero.
Q4: Why is subtracting a negative the same as adding?
Because you are removing a negative value, which increases the total.
Q5: Is zero a positive or negative integer?
