PEMDAS since we don't have exponentes or paretnahsees we do muliplictaion or division whichever comes first (since division is just multiplication of a fraction)
addition or subtraction whichever comes first (since subtraction is adding a negative)
so multiply/divide 0 times 3=0 9/3=3
now we have 5-0+3 add/subtract 5-0=5 5+3=8 answer is 8
