# The Year Game from NCTM

Updated: Feb 20, 2020

As a part of __NCTM____ __’s year-long 100th birthday celebration, they have created a year game for 2020.

__The Game__ is how many expressions you can write for all the numbers from 1 to 100 using only the digits of 2020.

__The Rules of the game;__

Use only the digits 2, 0, 2, and 0, in any order*, with the operations +, -, x, ÷, ^ (raised to a power), sqrt (square root), ! (factorial), and !! (double factorial) to write expressions for the counting numbers 1 through 100. Grouping symbols may also be used. This year, see how far you can get without using multi-digit numbers such as 20, 200, .02. However, the online submission form will still accept multi-digit numbers. Write your answers in the boxes above, using no equal signs. Correct format: ((2 - 0) * 2) + 0 Incorrect format: 2 - 0 = 2 * 2 = 4 + 0 = 4
