Answers to Questions

How to calculate a subtraction with big numbers?

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.

Example: $ 98765432109876543210 - 12345678901234567890 = 86419753208641975320 $

This is called large/huge number subtraction.

Why calculators and computers are limited with subtractions?

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)

How to read a subtraction a-b?

The mathematical reading is $ a $ minus $ b $

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

$ b $ subtracted from $ a $

$ b $ removed from $ a $

$ b $ withdrawn from $ a $
