the car plate game
PLAY electronically reconstructs
one of the maths games that Emilia Telese would play
with her father during long car journeys.
They would look at car registration plates and scramble their
numbers to get a score of 0 or 1.

rules:
you must use all the digits of the car plate, in any
order
for example:
H956BHL
5+6=11 1-1=0 9x0=0
you can use any mathematical operation to achieve the
result
for example:
FR114GT
÷4=2 1+1=2 2-2=0
you can use the numbers deriving from mathematic
operations from 2 or more of the numbers to achieve
your goal.
for example:
ABC146GH
1+4= 5 then take 5 and do 6-5= 1
if you need to, you can split the number deriving
from the first operation
and use the individual digits.
for example
Y567AGN
6x5=30 3+0+7=10 1-0=1
you can take the numbers in any order and do any
mathematical operation to achieve the result.
but you
have to take the numbers one by one in the first flush
of operations.
for example:
R961HLS
you can't consider this car as having 96 and 61 in it,
but 9, 6 and 1.
then, of course,
you can get 2 digit numbers from the
single digits,
for example
9x6=54 5-4=1 1x1=1
you can't use numbers again if you've already used
them once.
for example:
ABC 3585
5+5=10 8+3=11 11-10=1
(you can use 10 and 11 but you cannot use the
original four
numbers again)
