Use the digits in the year 2010 and the operations +, -, x, ÷, sqrt (square root), ^ (raise to a power), and ! (factorial) — along with parentheses, brackets, or other grouping symbols — to write expressions for the counting numbers 1 through 100.

All four digits must be used in each expression.

1. Only the digits 2, 0, 1, 0 may be used.

2. The decimal point may be used, as in .1, .02, etc.

3. Multi-digit numbers such as 20 or 102 may be used.
