With comments please; that way we can understand the alogorithms!

1. Write a complete MIPS-32 assembly language program including data declaration that uses a functionEval_Z which evaluates the following expression Z = X - 3 (Y / 8 + 125). Assume that callerprogram passes the values of X and Y to the function using registers $a0 and $a1 respectively whilethe result of executing the function is returned to the caller in register $v0. The caller program shoulddisplay the result on the console preceded by an appropriate message. Test your program using thefollowing values (X1, Y1) = (100, 24) and (X1, Y1) = (100, 21)

2.

Write a function N_SUM to find the sum of the integers from 1 to N. The value N will be passed to the

procedure in $a0 and the result will be returned in the $v0 register. Write a MIPS-32 assembly

language main program that will call the Sum function and print the result. Run your program using

MARS for the following values of N: 9, 32, and 777.
