Common Operations with Integers
When dealing with integers, you'll primarily perform the following operations:
- Addition ➕
- Subtraction ➖
- Multiplication ✖️
- Division ➗
Integer Addition and Subtraction
Adding and subtracting integers can be straightforward once you understand the rules. Here are some essential points to remember:
- When adding two positive integers, the sum is also positive.
- When adding two negative integers, the sum is negative.
- When adding a positive and a negative integer, subtract the smaller absolute value from the larger one and keep the sign of the number with the larger absolute value.
Example Problems:
| Expression | Answer |
|---|---|
| 5 + 3 | 8 |
| -4 + (-6) | -10 |
| -5 + 3 | -2 |
| 6 - 9 | -3 |
Integer Multiplication and Division
Multiplying and dividing integers follow specific rules as well:
- The product of two positive integers is positive.
- The product of two negative integers is also positive.
- The product of a positive and a negative integer is negative.
- Division follows the same rules as multiplication regarding signs.
Example Problems:
| Expression | Answer |
|---|---|
| 4 × 3 | 12 |
| -2 × -5 | 10 |
| -3 × 4 | -12 |
| 8 ÷ 2 | 4 |
