Friday Puzzler -- fix this equation

Alex Y

101-102=1

That's not right. There are [at least] two ways to fix it:

A: by moving one line

B: by moving one digit

Can you find both corrections?

I get the first, I'll have to cogitate about the number thing.

1 just move the equality.

Correct on A

Alex Y

Just move one line of the equals sign, putting it over the minus sign, so that the equation reads 101=102-1

I also found part B (moving a digit) much harder (never did get it), although once you see it, it is really easy.
