Try adding some of these together to look for the pattern:
-13 +16 = 3 odd+even = odd
-7 + 16 = 9
how about -13 + -7 = -20
-8 + 16 = 8
It looks like
even + even = even
odd + odd = even
even + odd = odd
So, we only get an odd result in this case. It seems that it is always true.
Can you find two other cases to support your answer?
John stated that when you add an even and an odd integer the answer will be odd. Use these numbers to answer the questions: –13, –8, 16, 23, –7 Is John’s statement always true, sometimes true, or always false? Write two equations to support your answer.
