Express number 1 by two distinct digits in as many ways as possible, using no mathematical signs.

The only ways I know to express a number without any mathematical signs are using concatenation, exponent as a superscript, and combination using parentheses and no fraction bar.

Concatenation: 01 = 1

Exponents:

1⁰=2⁰=3⁰=4⁰=5⁰=6⁰=7⁰=8⁰=9⁰ = 1

Combination is hard to render without big parentheses:

 1

( )  = C(1,0) = 1   etc...

 0  

Whether any of these counts is a matter of interpretation.
