The following table is the number chart from 1 to 100, where the odd numbers are highlighted in yellow and the even numbers are highlighted in green. Similarly, if ‘n’ is an odd number, then the next even number is ‘n + 1’, and the next odd number is ‘n + 2’, and so on.įor example, if we want to write a series of five odd numbers starting from 73, we can write it as: For example, if ‘n’ is an even number, then the next odd number is ‘n + 1’, and the next even number is ‘n + 2’, and so on. We can generalize the even and odd numbers as well. When we multiply two odd numbers, the result is always an odd number. It is a basic concept of maths, even numbers are the numbers that are divisible by two and as a result of we can say remainder we get zero.When we multiply an even number and an odd number, the result is always an even number.When we multiply two even numbers, the result is always an even number.When we add or subtract two odd numbers, the result is always an even number.For example,7 + 3 = 10.When we add or subtract an even number and an odd number, the result is always odd.For example,7 + 4 = 11.When we add or subtract two even numbers, the result is always an even number.For example,6 + 4 = 10.Therefor when he shows the function y x3 + 2. That is because y 2 is equivalent to y 2x0 and the number zero has even parity. We exclude division here because the division sometimes gives you the result in fractions while talking about special properties. And in the spirit of this video that connects 'even' and 'odd' functions with the parity (whether a number is even/odd) of it's exponents, the function y 2 is indeed even. Whenever we apply algebraic operations to two even or odd numbers, we always get an even or odd number. The odd and even numbers have special properties regarding algebraic operations (addition, subtraction, and multiplication). The above numbers are odd because they end with 1, 3, 5, 7, or 9. The above numbers are even because they end with 0, 2, 4, 6, or 8.
