lw $t0, 1200($t1)

add $t0, $s2, $t0

sw $t0, 1200($t1)

What is the MIPS machine language code for these three instructions?

1200 (in base 10) = 0000 0100 1011 0000 (binary)

$t0 register is number 8

$t1 register is number 9

$s2 register is number 18

Opcode -> lw is 35 (100011), sw is 43 (101011), R-type (000000) add func is 32 (100000)
