    Hope this helps for easy solution and better understanding:

    class Matrix{
    public: 
        vector<vector<int>> a;
        
        Matrix operator +(const Matrix& b){
            int n = a.size();
            int m = a[0].size();
            Matrix result;
            result.a.resize(n, vector<int>(m, 0)); // 2D vector mxn with entries=0
            
            for(int i=0; i<n; i++){
                for (int j=0; j<m; j++){
                    result.a[i][j] = a[i][j] + b.a[i][j];
                }
            }
            return result;
        }     
};
