Go Figure

Your goal is to create a true equation using all of the digits given to you. Numbers get used up once played; operators stick around for reuse. Play two numbers back to back with nothing between them to concatenate them into a bigger number — tap 1 then 2 to get 12, so 1, 2, 3, 4 can prove 12 ÷ 3 = 4. Beyond the basics, you've also got ^ for exponents, ! for factorials, and % for remainders. Use every number and add exactly one =, then press Check equation (or hit Enter) to see if both sides really match. Remember, there may be more than one solution! Good luck!
