Not all numbers are possible and for some numbers there are several solutions. Here are some examples: 0: (5x5)-(5x5) 1: (5:5)+5-5 2: (5:5)+(5:5) 3: (5+5+5):5 4: [(5x5)-5]:5 5: [(5-5)x5]+5 6: [(5x5)+5]:5 7: [(5+5):5]+5 10: 5+5+5-5 11: (5:5)+5+5 15: (5x5)-5-5 20: 5+5+5+5 24: (5x5)-(5:5) 25: (5x5)+5-5 26: (5x5)+(5:5) 30: [(5:5)+5]x5 35: (5x5)+5+5 45: [(5+5)x5]-5 50: (5x5)+(5x5) 55: [(5+5)x5]+5 75: (5+5+5)x5 120: (5x5x5)-5 130: (5x5x5)+5 625: 5x5x5x5
5x5 is 25 5x5 is 25 25x25 is 625
If you know what 5 cubed is then you will know what 5x5 is. But if you don't know the remember 5x4 is 20 and add an extra 5 to it!

No, not really - at least not for me (I'm 52yo) I think that the differences between the 4x4 and 5x5 are slight. It's one of those things where "if you can solve a 3x3 you can solve a 4x4 and if you can solve a 3x3 and a 4x4 you can solve a 5x5. The hardest part comes with the edges - there's some weird manuevers you have to do to get the edges right and oddly enough the 5x5 is easier on the edges than the 4x4 because the 5x5 has a center edge for each color and that makes it easier to get matches. It did for me anyway. But once I learned the 4x4, the 5x5 wasn't too hard to pick up.

This skills that someone has to solve a Rubik's cube can be used on any size Rubik's cube, whether it be a 2x2 or a 5x5.
5x5=25
(5x5)+(5x5)-(5/5)
5x5 - x - 5
