Make numbers 1 - 30 using the digits 2, 0, 1, 8
Rules:
Use all four digits exactly once
Allowed operations: +, -, x, ÷, ! (factorial), exponentiation, square root
Parentheses and grouping (e.g. "21") are also allowed
Squaring uses the digit 2 so expressions using multiple twos, like 22 or 12+82, are not allowed
Keep the order "2 0 1 8" in at least 25 expressions (and more if you can!)
The modulus operator is not allowed
Rounding is not allowed (e.g. 201/8=25)
