MIPS assembly instructions

1) Modify the piece of code so it can add 3 numbers.

2). What modifications were needed to add the 3 numbers?

-----MIPS Code-----

.data # variable declarations follow this line

.text # instructions follow this line

main:

## Code Part 1: Get first number from user, put into $t0.

ori $v0, $0, 5 # OUR CODE BEGINS HERE: load syscall read_int into $v0.

syscall # make the syscall.

addu $t0, $0, $v0 # move the number read into $t0.

## Get second number from user, put into $t1.

ori $v0, $0, 5 # load syscall read_int into $v0.

syscall # make the syscall.

addu $t1, $0, $v0 # move the number read into $t1.

add $t2, $t0, $t1 # compute the sum.

## Print out $t2.

addu $a0, $0, $t2 # move the number to print into $a0.

ori $v0, $0, 1 # load syscall print_int into $v0.

syscall # make the syscall.

ori $v0, $0, 10 # syscall code 10 is for exit.

syscall # make the syscall.
