Here is a small task with a simple mathematical equation. You are allowed to move one digit only, so that the equation is correct. You are not allowed to remove or add any characters!
62 - 63 = 1
How can this be? Any idea?
Have fun puzzling!

Move the 3 over 62 as an exponent and turn it sideways so it looks kinda like a fancy w. Then you have 62^w - 6 = 1. The equation IS correct, and has a real solution w = log 7 / log 62 = about 0.471492

62-63=1 because 2^6=64
