Sum of squares of integers is the sum of two squares, three squares, four squares or n squares. In arithmetic operations we have sum of n terms. But there are many techniques for the calculation of sum of squares. In statistics and basic algebra, we have various results using sum of squares. From beginning many famous mathematicians like Euler, Lagrange and Gauss have contributed a lot to develop the concept of sum of squares.
