Make 24
Using only the numbers 1, 3, 4, and 6 exactly once, the basic arithmetic
operators add, subtract, multiplication and division exactly once, and as many
parentheses as you want, write one equation that equals exactly 24.
For example, some possible (incorrect) solutions are: 1 + 3 * (4 / 6) = 3;
(4 + 3) * (1 – 6) = -35; (1 / 6) + 3 + 4 = 7.166
