Write a program to add $40($decimal$)$ and $-10($decimal$).$ There is no input, so these integers should be stored in memory. Output the result.

$2.$ Verify you can do the above program WITH INPUT. There is a video in this week$$s module called

Add$2$Integers

$3.$ Write a program to input an integer, add $10($decimal$)$ to it$,$ and output the result.

$4.$ Write a program to input an integer, subtract $20($decimal$)$ from it$,$ and output the result. There is no need for your initial integer to be greater than $20,$ your output will just be negative. Look at the status bits. If your result is negative N should be $1,$ if your result is zero, Z should be $1.$

$5.$ Write a program to input an integer, multiply it by $7,$ output the result. This is perhaps the most difficult, so be sure you can do this or ask for help.
