Alright, let's solve this math problem step by step. First, we have the number 480. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 9. So, we're going to take the number 480 and add it to itself 9 times.
Step 1: 0 + 480 = 480
Step 2: 480 + 480 = 960
Step 3: 960 + 480 = 1440
Step 4: 1440 + 480 = 1920
Step 5: 1920 + 480 = 2400
Step 6: 2400 + 480 = 2880
Step 7: 2880 + 480 = 3360
Step 8: 3360 + 480 = 3840
Step 9: 3840 + 480 = 4320

So, 480*9 = 4320
