Answer:
1100
Explanation:
What does it mean for a number to be odd or even?
An even number is a multiple of 2. For example, 2, 4, 6, 8, and 10 are all examples of that. An easy way to tell if a number is a multiple of 2 is by looking at the last number. 1674 is an even number, because it ends with a 4, whereas 1673 does not end with 0, 2, 4, 6...etc. making it an odd number.
The numbers 100-120 that are odd are:
(Remember, if a number is odd it ends in either 1, 3, 5, 7 or 9)
- 101, 103, 105, 107, 109, 111, 113, 115, 117, and 119
Adding them all together:
- 101 + 103 + 105 + 107 + 109 + 111 + 113 + 115 + 117 + 119 = 1100
Therefore, the sum of all numbers that are odd between 100 and 120 is 1,100.
