Odd Number
An odd number is a whole number that cannot be divided evenly by 2
An odd number is a whole number that cannot be divided evenly by 2. In other words, if you divide an odd number by 2, there will always be a remainder of 1.
Odd numbers can be identified by their last digit: they typically end in 1, 3, 5, 7, or 9. For example, 3, 7, and 9 are examples of odd numbers.
When we add or subtract odd numbers, the result will always be an even number. For example, 3 + 5 = 8, which is an even number. Similarly, 9 – 3 = 6, which is also an even number.
Multiplying two odd numbers will always result in an odd number. For example, 3 * 5 = 15, which is an odd number.
Odd numbers are used in many mathematical contexts, including prime numbers (which are odd numbers greater than 1 that cannot be divided evenly by any other number except 1 and itself) and in patterns and sequences. They are also important in understanding concepts such as divisibility and remainders in number theory.
