yeah? well my function is even larger!
say you have 2, 2 as the arguments.
you then add the first to the second, and turn the second into the result:
2, 4
you then multiply the first and second, and turn the second into the result:
2, 8
you then raise the first to the power of the second, and turn the second into the result:
2, 256
you then add the first by the second, and turn the second into the result:
(you repeat this process the amount of times that the second argument is)
2, 258
you then multiply the first and second, and turn the second into the result:
2, 516
you then raise the first to the power of the second, and turn the second into the result:
2, 214524926879081553593184399971293538039669853129478294043576983099548224481176751628829988770670454843040509730983776813660062124991145119142938384097345536
you then raise the first to the power of the second, and this is the final result:
