Hi everyone. I'm fairly new to programming with spim. This is the first time I've tried to multiply numbers and I keep getting errors!
I looked up on 'SPIM quick reference' how to do multiplication but can't get it to work.
Any help would be greatly appreciated :)
PS. I hope my code is readable, apologies if its not to standard coding practices
.data
.text
.globl main
main:
li $v0, 5 #read int (x)
syscall
# first int is stored in $v0
move $s0, $v0 # first int in $s0
# read in 2nd int
li $v0, 5 # read int (y)
syscall
#2nd int is stored in $v0
move $s1, $v0 #2nd int in $s1
# x^2
mult $s2, $s0, $s0 # x^2 is in $s2
# 4y^2
mult $s3, $s1, $s1 # y^2 is in $s3
mult $s3, $s3, 4 # 4y^2 is in $s3
# 4xy
mult $s4, $s0, $s1 # $s4 is xy
mult $s4, $s4, 4 # $s4 is 4xy
# -6y
mult $s5, $s1, -6 # $s5 is -6y
# Put it all together
add $s6, $s2, $s3
add $s6, $s6, $s4
add $s6, $s6, $s5
addi $s6, $s6, 9
#print it
move $a0, $s6
li $v0, 1
syscall
li $v0, 10 # exit
