Addition of Matrices
​
If [A] and [B] are two matrices of same order, [A] + [B] is defined as matrix formed by sum of corresponding elements.
Addition
Square Matrix as a Sum of Symmetric and Skew-Symmetric Matrix:
Symm+skew symm
where,
(M + Trnas. of M) is a Symmetric matrix.
(M - Trnas. of M) is a Skew-Symmetric matrix.
​
In this way, any square matrix may be written as the sum of its symmetric and skew-symmetric parts.
​
Example:
​
GATE 2020: A matrix P is decomposed into its Symmetric part S and Skew-Symmetric part V. Find the matrix P.

Solution:
​
Matrix M = Symmetric part + Skew-Symmetric part
M = S + V
Adding S & V, M comes out to be

So, B is the correct answer.
