There might be a difference between adding numbers by inspecting their 
structure and going through some kind of algorithm that composes a new 
number digit by digit based on the digits of the numbers it's adding.
As opposed to a kind of look-up table with pre-computed sums where it 
just looks up the particular combination of inputs to find the 
associated output.

Just like if you have some complicated function that takes long to 
compute which is showing down your algorithm, you can compute it once
and keep the results in a kind of table that enables you to retrieve the
precomputed value without going through the same calculations repeatedly 
and discarding the results every time.
