Study Notes
Integers
- Integers are whole numbers, either positive, negative, or zero, without a fractional part.
- Examples of integers include ..., -3, 0, 1, 2, ...
Identifying Integers
- Not all whole numbers are integers; for example, fractions, decimals, and mixed numbers are not integers.
- To determine if a number is an integer, check if it has a fractional part; if it doesn't, it's an integer.
Integer Operations
- When an integer is added to its negative counterpart, the result is always zero.
- For example, 5 + (-5) = 0, or -3 + 3 = 0.
