To determine whether the sum of several numbers is even or odd, you can count the number of odd and even numbers in the set. If there are an even number of odd numbers, the sum will be even; if there is an odd number of odd numbers, the sum will be odd. For the numbers 13, 45, 24, and 17, there are three odd numbers (13, 45, and 17) and one even number (24), so the sum is odd.
3 + 4 +10 = 17 is a number sentence that has a sum of 17. 4 + 13 = 17 is also a number sentence that has a sum of 17. Here are some more number sentences: 10 + 10 - 3 = 17 21 - 4 = 17 There are many ways to write a number sentence that has a sum of 17. What other ways can you think of?
The prime numbers between 10 and 20 are 11, 13, 17, and 19.
