Write proper main method to create matrix objects to test your functions.

$([a,b$

$c,d])+([e,f$

$g,h])=([a+e,b+f$

$c+g,d+h])$

$([a,b$

$c,d])-([e,f$

$g,h])=([a-e,b-f$

$c-g,d-h])$

$\left[\begin{array}{ccc}{a}_1& b_1& d_1\end{array}\right]$

$c_1\left[\begin{array}{ccc}{a}_2& b_2& d_2\end{array}\right]$

$c_2=\left[\begin{array}{ccc}{a}_1{a}_2+b_1{c}_2& a_1{b}_2+b_1{d}_2& c_1{b}_2+d_1{d}_2\end{array}\right]$

$c_1{a}_2+d_1{c}_2$
