Puzzles | Arithmetical puzzles | Four 4's equal...

Use exactly four 4's to form every integer from 1 to 50, using only the operators ' + ', ' − ', '$\times$', ' / ', '()' (brackets) x² (square), and '!' (factorial). The square and factorial operators should be used as sparingly as possible. 44 will not be a valid application of the number 4 and the simpler solution, requiring less operations, will be the valid one.
