Hypermathematics

Hypermathematics is a variant of mathematics. It uses as base function concatenation instead of addition. Concatenation is gluing two numbers together, so in hypermathematics is 2+2 equal to 22. Another example: 43+43=4343.

Multiplication
It should be noted that in hypermathematics, multiplication isn't commutative nor assiociative, in contrast to normal mathematics. A chain of multiplications should be solved from the right to the left. Example:

\(3 \cdot 3 \cdot 3 = (3+3+3)\cdot 3 = 333 \cdot 3 = \underbrace{3+3+3...3+3+3}_{333}\)

The expression above is equal to \(10^{334}-1\) using normal mathematics.
