To combine two positive numbers without using the * operator (or / operator), create a recursive code. You can use bit shifting, addition, and subtraction, but you should use them sparingly.

Programing C Just with #include Matrix Addition and Subtraction (Associatively) Write a program that performs matrices addition and subtraction. As shown in the example below, you have to ask the user for the number of rows and number of columns that both matrices should have (they both have to be the same size, that is why you only ask once). You will then ask the user for the values of each matrix. Then, you will print the values that the user inputted, the added values of both matrices, and the subtracted values (matrix 2 should be subtracted from matrix 1). In this challenge Guidelines/steps: • The number of rows and the number of columns should be global variables. • Once you get these two from the user, you should declare your two matrices in main. • Then, from main, you will call function aaa twice; first, you will send matrix 1 and populate it with values inputted by the user. You will call the function a second time, send matrix 2 and populate it. In other words, function aaa…

Part 3: Negative Binary Numbers This standard method of binary number representation doesn't account for negative numbers. We can't just throw a negative sign in front of a binary number though - everything in a computer must be represented by 1's and 0's. One way we can get around this is by using the very first digit of each binary number to represent the sign: 0 for positive and 1 for negative. This is called 1's complement representation. 00010110  ->  0  0010110  ->  positive 22 10010110  ->  1  0010110  ->  negative 22   Using 1's complement representation we can represent the numbers -127 through 127 in a single byte (note that we can only go half as high as an unsigned number because half of the possible representations for that byte are being used for the negative numbers). However, there is a flaw with 1's complement: the representation of the number 0. 00000000  ->  0  0000000  ->  zero 10000000  ->  1  0000000  ->  negative zero? Because of this, we…
