Computer Science homework help

I have to create a matrix with unique pointers and do the following :
1.Matrix a, b
2.Matrix c(b)
3.Matrix d=a
4.Matrix e=a+b
Every element from matrix is a unique pointer. First, I have to create a class matrix with constructor destructor(rule of 5 if it is possible).
At first in main, I have to create 2 object a, b, Matrix type.
At 2.I have to create another object c that have as constructor the object b
3.to copy all element from matrix a to d
4.To add Matrix a with Matrix b and the sum to be copy in Matrix e
