Largest Number

What's the largest number you can make with just two digits?

I would say the alrgest is 9E9...that's two digits (plus one letter) and is 9 billion.

Along the same lines, smallest would be 1E-9...one billionth. (Unless you want to include negative numbers, in which case it would be -9E-9, negative nine billion)

I was avoiding letters, so I came up with 9^9 = 387,420,489. You can go negative for the smallest number (I was thinking closest to zero, rather than negative).

Leave your answer or, if you want to post a question of your own, send me an e-mail. Look in the about section to find my e-mail address. If it's new, I'll post it soon.

ReplyDeleteIn that case, you could just use 9T (T for terra)

ReplyDeleteBut your answers make sense to me.
