All of the players in the car pick a license plate number together, for example, 9MBR318. Eliminate the letters, which leaves the numbers 9, 3, 1, and 8. Using only the numbers from the license plate and the processes of addition, subtraction, and multiplication, each player tries to create as many new numbers as possible from 1 to 10 in a designated time frame. Here are some new equations using the numbers in our example:
9 – 8 = 1
9 – 8 + 1 = 2
3 x 1 = 3
9 – 8 + 3 = 4
8 – 3 = 5
9 – 3 = 6
9 – 3 + 1 = 7
8 x 1 = 8
9 x 1 = 9
9 x 1 + 1 = 10
The first carschooler to make equations that represent all 10 numbers wins. If no one can make all the numbers from 1 to 10, the person who made the most numbers wins. Carschoolers can create some very complicated equations to get to the numbers they need, but remind them they can only use the numbers in their license plate.
