The New Year Challenge



Every year from 1968 until 1999, I posed the following challenge to my students:

Write expressions for all the numbers from 1 to 100 using only the digits in the current year in order and using the operations +, -, x, ÷ , ^ (raised to a power), sqrt (square root), and ! (factorial), along with grouping symbols.
