Integer Operations Explained
Understanding how integer operations work is important for mastering math. Let’s break it down.
1. Addition of Integers
Addition means combining two numbers into a single value.
Formula:
a + b = Result
Rules:
- Positive + Positive = Positive
- Negative + Negative = Negative
- Positive + Negative = Subtract values and keep sign of larger number
Example:
- 8 + 5 = 13
- (-4) + (-6) = -10
- 10 + (-3) = 7
2. Subtraction of Integers
Subtraction means finding the difference between two numbers.
Formula:
a − b = Result
Important Rule:
Subtraction can be converted into addition:
a − b = a + (−b)
Example:
- 10 − 4 = 6
- 7 − (-3) = 10
- (-5) − 2 = -7
Addition vs Subtraction of Integers (Comparison Table)
| Operation | Rule | Example | Result |
|---|---|---|---|
| Addition | Combine values | 5 + 3 | 8 |
| Addition | Different signs | 6 + (-2) | 4 |
| Subtraction | Convert to addition | 9 − 4 | 5 |
| Subtraction | Negative subtraction | 8 − (-3) | 11 |
| Subtraction | Negative numbers | (-7) − 2 | -9 |

Solution:
15 − 9 = 6
Example 4: Subtracting a Negative Number
Input:
- First Number: 10
- Second Number: -5
Solution:
10 − (-5) = 15
Example 5: Mixed Integer Operation
Input:
- First Number: -8
- Second Number: 3
Solution:
-8 − 3 = -11
Integer Rules You Must Remember
Here are some important rules to avoid mistakes:
- Two positive numbers always give a positive result
