Assuming by "numbers" you mean "digits":

99

9 9 = 81 (in algebra multiplication is not written as it could be confused with the letter x, so two symbols written next to each other are multiplied together)

99 (nine to the power 9) = 387,420,489

99 (the tetration of 9 nine times, ie 9 to the power of 9 to the power of 9 to the power of...to the power of 9) which is extremely large.

Also, by using a base for the numbers higher than base 10 (eg hexadecimal = base 16) even higher numbers can be reached.
