Partners pretend that one of the number
keys is broken. One partner says a number, and the other tries
to display it on the calculator without using the "broken"
key.
Example:
If the 8 key is "broken," the
player can display the number 18 by pressing 9[+]7[+]2, or 9[x]2, or
72[÷]4.
Scoring:
A player's score is the number of keys
entered to obtain the goal. Scores for five rounds are totaled
and the player with the lowest total wins.
