I am in 8th grade and we are learning about Transformations - Reflections & Rotations Activity and I don't know how to do it

-prime numbers are 2, 3, 5, 7
-zero can only go in the second or third number
- so you could do 1×10, 2×10, 3×10, 4×10, 5×10, 6×10, 7×10, 8×10, and 9×10 in the second digit
- you can also do this in the third digit 5× only because you can't double a number and you still have to do your last prime numbers
-in the first digit you can only do a number once

I'm not sure what my answer is cause I'm half asleep sorry
