ODD AND EVEN NUMBERS A number can be identified as odd or even. Odd Numbers If a number is 1,3,5,7, or 9 or if it has 1, 3, 5, 7, or 9 in the ones place, it is identified as an odd number. If you have a number that is more than one digit long, such as 267, you must look at the ones place, the last digit, to tell if it is an odd number. In the number 267, the 7 is in the ones place and 7 is an odd number; therefore 267 is an odd number. Here are some examples of odd numbers: Even Numbers If a number is 2, 4, 6, or 8 or has 0, 2, 4, 6, or 8 in the ones place, it is identified as an even number. If you have a number that is more than one digit long, such as 492, you must look at the ones place, the last digit, to tell if it is an even number. In the number 492, the 2 is in the ones place and 2 is an even number; therefore 492 is an even number. Here are some examples of even numbers: 1 7 27 143 1,295 3 9 39 495 6,227 5 11 61 827 9,999 2 8 24 174 1,370 4 0 36 418 5,496 6 12 68 782 9,000 © Copyright NewPath Learning. All Rights Reserved.
