Kakooma starts with a deceptively simple idea: in a group of numbers, find the number that is the sum of two others. Sounds easy, right? Sometimes it is, but other times the answer is right in front of you and you just can’t see it. To solve a single puzzle, you often end up doing dozens of calculations in your head, sometimes more than a hundred! Before you know it, your mind is sharper and your math skills are better. Kakooma makes you smarter.
This bundle includes 205 pages of puzzles using positive and negative numbers ranging between the numbers 1 and 25.
