DEV C++, create a program to perform matrix multiplication, and will let the user input two square matrices. With a maximum of 10 x 10 matrices. If the user inputs negative matrices, more than 10 matrices, or 1 matrix the program should display “Invalid.”   If the user inputs n = 3 First matrix: -35  54  64  31  45  -12  17 -31 -19    Second matrix: 69  90 -85  29  52 -19  37 -26 -97 Output:  587       9249     14127   -8656   -8711     1326  -6610    14754   14694 If the user inputs n = 2

Q2} Write a user-define function that add or subtracts two polynomials of any order. Use the function to add and subtract the following f₁(x)=x5-7x4+11x³-4x²-5x-2 and f₂(x)=9x²-10x+6 polynomials:

Apply your knowledge about arrays and functions and write a program, which takes a positive integer N from user, and prints the multiplication table of the size N by N. For Example, if the user enters 10 then your program should display the following table. Note: your program should have a function naming "Multiplication" which should take size N as input argument. Output should be in this format. 1 2 3 4 5 6 7 8 9 10 71 81 91 10 I 1 I 21 31 4 1 4 51 5 61 6 12 7 8 16 24 1 123 2 3 4 5 6 7 8 9 8 10 12 14 16 18 12 15 18 21 24 27 16 20 32 36 20 25 30 35 40 45 18 24 30 36 42 48 54 35 42 49 56 63 70 32 40 48 56 64 72 80 36 45 54 63 72 81 90 20 30 40 50 60 70 80 90 100 2 3 6 6 9 8 12 10 24 10 15 14 21 28 9 18 27 24 28 10 20 30 40 50 60

[Python (py3)] Displayed below is a code for matrix addition. However, there is an error that should be fixed in the code. The error in the code below is if the number of rows of the matrix is not equal to the number of columns of the same matrix, matrix addition will not be performed. This should not be the case so please fix this error. The only requirement for matrices addition is that the dimension of Matrix A is equal to the dimension of Matrix B, regardless if the number of rows of Matrix A and Matrix B is equal to the number of columns of Matrix A and Matrix B, respectively (see sample input and output below).Please resolve the error in the code below such that Matrix A and Matrix B can be added if the dimension of Matrix A is equal to the dimension of Matrix B. PLEASE do not just copy the code below and use it as the answer itself. I've encountered such case many times. Please modify the code. When the dimension of Matrix A is not equal to the dimension of Matrix B, print…
