7 squared is 49 and 5 squared is 25. So the difference is 49-25=24
7 and 2 are the prime numbers having a difference of 5.
It's hard to explain without using the word difference, but here's an example: The difference between 5 and 7 is 2. 7 minus 5 = 2

The numbers are 7 and -5 because 7-(-5) = 12 and 7+(-5) = 2
7 and 2 are the prime numbers having a difference of 5.
The result will always be a negative value. The difference can be looked upon in a neutral way, or depending on the calculation, you may want to say there is a difference by a particular sign. We would normally look on the difference in a positive way. -7 - 5 is - 12. The difference between -7 and -12 is 5. However if you are going from -7 to -12 you have a -5 difference, while going from -12 to -7 you have a 5 difference. So it can depend on perspective.
9. 92 = 81. The difference of the digits 8 and 1 is 7.
