Study Notes
Definitions
-
Even Numbers
- Integers that are divisible by 2 without a remainder.
- Can be expressed in the form: ( n = 2k ), where ( k ) is an integer.
- Examples: -4, -2, 0, 2, 4, 6, etc.
- Characteristics:
- The last digit is 0, 2, 4, 6, or 8.
- The sum of two even numbers is always even.
- The product of two even numbers is always even.
-
Odd Numbers
- Integers that are not divisible by 2, leaving a remainder of 1 when divided by 2.
- Can be expressed in the form: ( n = 2k + 1 ), where ( k ) is an integer.
- Examples: -3, -1, 1, 3, 5, 7, etc.
- Characteristics:
- The last digit is 1, 3, 5, 7, or 9.
- The sum of two odd numbers is always even.
- The product of two odd numbers is always odd.
