Answer 1

To write a SPIM assembly language program equation.s based on the example program math1.s, follow the steps: prompt the user for a value of X, store the input, perform calculations, and display the result.

Step-by-step explanation:

To write a SPIM assembly language program equation.s based on the example program math1.s, you can follow these steps:

1. Prompt the user to enter a value for X.
2. Store the user input in a register.
3. Perform the necessary calculations using the stored value.
4. Display the result to the user.

Here is a sample code for the program:

.data
prompt: .asciiz "Enter a value for X: "
result: .asciiz "The result is: "

.text
.globl main

main:
li $v0, 4
la $a0, prompt
syscall

li $v0, 5
syscall
move $t0, $v0

# Calculate the equation
mul $t0, $t0, 2
addi $t0, $t0, 10

# Display the result to the user
li $v0, 4
la $a0, result
syscall

li $v0, 1
move $a0, $t0
syscall

# Exit the program
li $v0, 10
syscall

This program prompts the user to enter a value for X, stores the input in a register, calculates the equation by multiplying the value by 2 and adding 10, and then displays the result to the user. The program then exits.
