How to do mathematical accounts with a calculator

The term "sum" is used in mathematics to describe the result of adding two or more numbers. Finding the sum of two or more numbers is one of the most elementary operations of arithmetic and is a necessary skill to master before moving on to higher forms of mathematics. There are a couple of ways to do the sums : you can use a calculator or you can write your math problems to find the sums at hand.
