I need help with making some programs in MIPS assembly language programming (example mul $t2, 3). Here is my assignment:

Write programs to evaluate the following expressions. The user should enter the variables, and the program should print back an answer. Prompt the user for all variables in the expression, and print the results in a meaningful manner. The results should be as accurate as possible.

a) 5x + 3y + z

b) ((5x + 3y + z) / 2) * 3

c) x³ + 2x² + 3x + 4

d) (4x / 3) * y
