Even Integers
The integers which can be divided by ‘2’ with “0” as remainder, is known as even integer. Like 2, 4, 6,8,10 …… all are even integers.
Odd Integers
The integer which cannot be divisible by ‘2’ or in other words when we divide any number by ‘2’, there is some remainder then it is an odd integer. Like 1, 3, 5, 7, 9…… are all odd integer.
Rules and facts about even and odd integers
- Addition of two even integers is even
4+6 =10
12+16 = 28
- Addition of two odd integers is even
3+5 = 8
7+11=18
- Adding one even integer and one odd integer is odd integer
3+2=5
8+7=15
- Multiplying two even integer results in even integer
6 x 8 = 48
- Multiplying two odd integer results in odd integer
7 x7 = 49
- Multiplication of one odd integer and one even integer results in even integer
3 x 8 =24
