Your assignment is to write a program that inputs two square matrices and then calls functions that you create that add, subtract, and multiply the two matrices. your program must first ask the user the size of the square matrices that are to be used. this must be a number from 2 to 6. next, the user is requested to enter the two matrices. make certain that you display good directions(using print statements) on how this input is to be done! next, the program prints out the two matrices and then invokes the three functions. the first function adds the two matrices, the next subtracts the second from the first, and the third multiplies the two matrices. the program must print the results of these operations after each of the functions returns. make certain to output these matrices in a way that is easy to read and understand!
