Using numbers 1,3,4,6, and basic arithmetic operations (addition, subtraction, multiplication, and division) and parentheses, obtain and expression that evaluates to 24. You may use only these numbers and only these operations. Every number should be used exactly once. Numbers cannot be concatenated, i.e. you cannot use 13 or 146.

is this even possible? after bashing my head against it for a while, ran a simulation in Excel - no permutation of numbers and operators actually produces a 24... (parentheses simulated by ignoring order of operations and simply ordering the numbers)

A lot of people have done this. I suppose, this is easier when you use only your head ;)

"obtain AND expression that evaluates to 24." Is this a typographical error and should say "obtain AN expression..."; or is it correct as it stands?
