Sure thing, let's get straight to it. We start with 480 and we're going to multiply it by 18, which means adding 480 to itself 18 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
Step 10: 4320 + 480 = 4800
Step 11: 4800 + 480 = 5280
Step 12: 5280 + 480 = 5760
Step 13: 5760 + 480 = 6240
Step 14: 6240 + 480 = 6720
Step 15: 6720 + 480 = 7200
Step 16: 7200 + 480 = 7680
Step 17: 7680 + 480 = 8160
Step 18: 8160 + 480 = 8640

So, 480*18 = 8640
