- The game generates 10 random maths problems one-by-one.
- It randomizes the numbers with a a number range of 1-11 for the first number and 1-30 for the second number
Children do not know the validity of basic mathematical proofs that adults take for granted. Also, negative-numbers can be quite tricky (too abstract) for young kids. Considering this the game is consciously designed to never generate problems where the answer is less than 0.
a + b == b + a
(This proof is self-evident for adults. But not for young children)
