Summary

Code to solve 4 4's problem : write each of the numbers 1 to 100 using exactly four 4's for each number

now for each function,make a function that performs on the first element, and keeps a record in the 2nd

Now we start making lists of numbers, starting with numbers reachable from one 4: 4,  .4 = 4/10, and .4 repeating = 4/9, and we apply all unary ops to them

Solutions for the first 150 integers….
