Odd + even = odd
The sum of one odd number and one even number is another odd number.
Any pair of one even and one odd number will have an even product and an odd sum.
no
The sum of two odd numbers is always even.
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.
The sum of one odd number and one even number is another odd number.
No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even
Any pair of one even and one odd number will have an even product and an odd sum.
The 4 is even. The 5 is odd. Their sum, 9, is odd. The sum of (one even number) + (one odd number) is always odd.
The sum of an odd and even number is always odd because there's always one left over. Think of any odd number as being any even number plus one. If you add two even numbers, the answer is always even. If you add an even and an odd (plus one), the answer is always odd.
