Subtraction

Subtraction is the arithmetic operation that involves subtracting one value from another. It allows you to calculate the difference between two numbers.

In computers or on a calculator, subtraction is limited by the storage capacity of numbers (number of bits available) to about ten digits.

For very large numbers, dCode uses specific algorithms to perform subtraction without loss of precision.

The dCode subtraction tool with big integers is based on arbitrary precision calculation algorithms allowing to subtract exact values without truncating to a defined precision nor need of a scientific notation up to several thousand digits.

This is called large/huge number subtraction.

Electronic tools and programs store numbers in memory cells of finite size, unlike numbers that can be way more bigger in size (theorically infinite). Thus, calculator subtractions can not generally exceed 10 digits, and computers are generally limited to 32 bits subtractions (2 ^ 32 = 4294967296 or 10 digits) or 64 bits (2 ^ 64 = 18446744073709551615 or 20 digits)

The mathematical reading is $ a $ minus $ b $

But in a more literary way, it is possible to read:

$ a $ take away $ b $

$ b $ subtracted from $ a $

$ b $ removed from $ a $

$ b $ withdrawn from $ a $

When $ b > a $, the result of subtracting $ a - b $ is negative.

Verify a subtraction by performing the inverse operation.

If $ a - b = c $, then verify that the addition $ c + b = a $ is true
