Question Mark Notation

(Please note that question marks can be used differently in math!)

Question Mark Notation is a notation created by galac2928. It features question marks to define large numbers.

Lets define this short series:

10?[10]

This means 10^^^^^^^^^^10.

Impressed yet?

Now see this:

10?[10][10]

This is a number with 10?[10] arrows.

Giant! But we haven’t even scratched the surface yet!

10?[10][10][10]

This is basically just defining that the number has 10?[10][10] arrows.

Uh oh, what is wrong with the next array?

10?[10][10][10][10][10][10][10][10]

The array is way too large!!! How do we solve this?

10?[10](8)

If a number is in than that means it defines how many [ ] there is because the last one has eight tens.

Let’s look at them grow!

10?[10](100)

10?[10](10^100)

10?[10](10^^^^^100)

10?[10](10?[10](10^^^^^^100)

But what does it mean if there is double question marks? It means that it’s defining how many times a sequence of arrays is in the array. Example:

10??[10]((30))

The double means how many times an array part is in the sequence. Example:

10?[10](10?[10](10^^^10?[10](10?[10](10^^^10) would be 10??[10]((2)) because there are two arrays inside the array.

Anyways, let’s continue!

10??[10]((10^^50))

10??[10]((10?[10^^^10]))

10???[10](((10^10)))

I think you understand what it means now when there are more than one bracket and question mark.

10?(?10)[10](100)

If there is a question mark behind a number in the sequence than it defines how many ? and there is.

10?(?10^^^100)[10](500)

10?(?10??[10]((10?[10^^^10]))

Even though larger numbers can be made with this, this is the farthest I will go.
