Use exactly four 4's to form every integer from 1 to 50, using only the operators '$+$', 'Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "http://localhost:6011/en.wikibooks.org/v1/":): {\displaystyle -} ', '$\times$', '$/$', '()' (brackets) $x^{2}$ (square), and '!' (factorial). The square and factorial operators should be used as sparingly as possible. If 44 (which is 4 x 10 + 4) can be avoided, avoid it. In this version of the problem, the square root operator is not allowed.
