Plus Eight

Operators+ is a puzzle game that challenges your arithmetic skills.
Each level shows four numbers and three operations. Starting from the first number, use various combinations of the three operations to get to each following number. Do so using the fewest operations possible.
As the difficulty increases, new operations are added. Starting with addition and subtraction and solutions that are under ten steps in the easy levels, the hardest levels include square roots and up to nineteen steps!
This game is deceptively simple and pushes you to think outside the box.
