## calcMod-Blk Description
What are all the digits of the factorial of 69 and how many digits ?
What is the gogol number ?

How many integers of the form 10^n+1 are prime ? (like 101)

Want to know if a big integer is prime ? The change mod function indicates when the number is prime.

You can stoke one number and recall it when you want.

The "Mod" operation indicates the residue modulo N.

The "pow" function allow modular exponentiation (as + - *)
