Modular inverses (article) | Cryptography | Khan Academy
Division doesn't exist in modular arithmetic. However, many of the things we can do with modular inverses act the same as or similar to division. e.g. if we have a * k ≡ b * k (mod C) where k is …
Fast modular exponentiation (article) | Khan Academy
Last 12 digit means take the mod 10^12 of the result 2^34 = 17179869184 Which is a power of two so the binary representation only has the 34th bit set. So in this simple case we can do …

Modular exponentiation (article) | Khan Academy
These huge values cause our calculators and computers to return overflow errors. Even if they didn't, it would take a long time to find the mod of these huge numbers directly.
