2nd: Write the four digits of your birth year
[ex. 1949 becomes 1, 4, 9, and 9].
3rd: Using the digits of your birth year as 4 numbers,
and using any operation you wish
[+, -,, X, , , 1/x, x (where x and n are two of the four numbers)] and as many parenthesis as you wish, write
an expressions equal to each whole number from 0 to 10.
Ex: 0 = (9 - 9)(4 - 1)
