MathGolf
You are given three numbers. Your goal is to include the three numbers
in an equation, using a combination of addition, subtraction, multiplication,
division, exponents, and roots (along with parentheses, if you wish).
You may use each number only once, but you may use the three numbers
in any order. However, you can't combine digits. For example, if you were given 1, 2,
and 3, you can't use the number 12 or 23 or any other such combination in your
equation.
Your score is how far your answer is from the target number
(absolute values only, no negative numbers).
For each set of three numbers (a hole), write down your equation,
your answer, and your score. Send us your best shots, using the form below. We'll post a selection of your
answers.
