Number Challenges

Instructions for Solving Perimeter Puzzles

In these puzzles, you are given eight equations. You must insert mathematical symbols (no digits) to make each equation equal six. If you are wondering what mathematical symbols you are allowed to use, that is up to you!

The only restriction is that you cannot add any digits to the equation. This includes adding exponents. Feel free to use addition, subtraction, multiplication, division, roots, factorials, and concatenation.

  • MIND YOUR 4s. Use four 4s and any operations you can think of to get the mathematical operations, anything goes! The basic arithmetic operations +, -, ×, ÷ along with exponents, roots, decimals (4.4 or .4), concatenation (44), percentages, repeating decimals (.44…), are all allowed. Remember to include exactly 4 4s (that's four fours).
