Unsigned Int

Challenge your integer skills in this math integer puzzle game with 20 levels to complete. Use all of the integer orbs to come up with a final answer of zero while not going below zero and staying below 21. The first few levels start out easy with just adding positive and negative numbers. Later levels use multiplication and division making levels more difficult. That isn't a problem as you are given the option of seeing the solution and trying again if you make an error or run out of time.

Click on integer orbs to use them and their operation in the running total. Division can only be used when the answer results in a whole number. If the running total goes below zero, above 20 or you run out of time, you will be given the option to try again or see the solution. If you choose to see the solution you will be shown the steps used to complete the level. Once the solution is shown, you will be given the option of seeing the solution again or trying it out yourself.
