Answer:
11 and 51
Step-by-step explanation:
1 technically isn't a prime since a prime can only be divided by two things (itself and 1) and 1 can only be divided by 1.
21 can be divided by 1, 3, 7, and 21 so it is not prime.
Hope this helps!
An integer is a whole number, in other words, a number that isn't a fraction or decimal.
0 + 0 + -2 + -2 + 2 + -2 = -4
-4 is an integer because it is not a fraction or decimal.
Best of Luck!
