Hyperinteger

A hyperinteger is a number that is bigger than any normal number that you can count. Instead of counting in ones, twos, threes and so on, a hyperinteger is a number so big that you cannot count that high. Hyperintegers are usually used in maths and science to figure out things that are really hard to figure out.
