Understanding Large Number Arithmetic
Large-number arithmetic follows the same mathematical rules as normal arithmetic. The only difference is the size of the numbers involved.
Addition Formula
Addition combines two values into a larger total.
Formula
A+B=Result
Example
999999999999+1=1000000000000
Subtraction Formula
Subtraction removes one value from another.
Formula
A−B=Result
Example
1000000000000−1=999999999999
Multiplication Formula
Multiplication repeatedly adds a number to itself.
Formula
A×B=Result
Example
999999×999999
Result:999998000001
Division Formula
Division separates a number into equal parts.
Formula
A÷B=Result
Example
1000000000000÷10=100000000000
