Tool to make multiplication with large numbers. Multiplication is a basic arithmetic operation defined as the repetition of an addition. 3 times 2 = 2+2+2. Standard calculators are limited with big numbers.
dCode uses arbitrary precision algorithm in order to get exact values without scientific notation.

In order to improve calculation time the multiplication is accelerated by decomposing it:
ab * cd = (a * 10^k + b) * (c * 10^k + d) = ac * 10^2k + (ad + bc) * 10^k + bd
This multiplication needs 4 values ac, ad, bc and bd. More :
(a * 10^k + b) * (c * 10^k + d) = ac * 10^2k + (ac + bd - (a - b)(c - d)) * 10^k + bd
The same multiplication needs 3 values : ac, bd and (a - b)(c - d).
