# How to add/subtract large numbers using Python?

PythonProgrammingServer Side Programming

You can add/subtract large numbers in python directly without worrying about speed. Python supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long and is separate from the int type, but the interpreter will automatically use whichever is more appropriate.

As long as you have version 2.5 or better, just perform standard math operations and any number which exceeds the boundaries of 32-bit math will be automatically (and transparently) converted to a bignum.

## example

a = 182841384165841685416854134135
b = 135481653441354138548413384135
print(a - b)

## Output

This will give the output −
