what's the highest number number?
Surprisingly, only 70 people. 3. But a googol isn't the largest named number. A googol is 1.0 x 10 - a one followed by 100 zeros. An even bigger number is the googolplex, which is 1.0 x 10googol-a one followed by a googol of zeros. Now, let's get an idea about the size of a googolplex. Ok, let's stop there. That isn't a googolplex, it's a one followed by 1,000 zeros.
There is no largest number. One simple way to consider this is to  look at the function:    f(x) = x + 1    Pick any number, and plug it into that function. No â¦ matter what  number you plug in, the function will always give you a number that  is one larger than the previous one. It doesn't matter how big x  is, there will always be an x + 1 value, which will always be  larger than x.
