OK, let's crack this. We're given 180 and our task is to multiply it by 24. Essentially, we'll be adding 180 to itself 24 times.
Step 1: 0 + 180 = 180
Step 2: 180 + 180 = 360
Step 3: 360 + 180 = 540
Step 4: 540 + 180 = 720
Step 5: 720 + 180 = 900
Step 6: 900 + 180 = 1080
Step 7: 1080 + 180 = 1260
Step 8: 1260 + 180 = 1440
Step 9: 1440 + 180 = 1620
Step 10: 1620 + 180 = 1800
Step 11: 1800 + 180 = 1980
Step 12: 1980 + 180 = 2160
Step 13: 2160 + 180 = 2340
Step 14: 2340 + 180 = 2520
Step 15: 2520 + 180 = 2700
Step 16: 2700 + 180 = 2880
Step 17: 2880 + 180 = 3060
Step 18: 3060 + 180 = 3240
Step 19: 3240 + 180 = 3420
Step 20: 3420 + 180 = 3600
Step 21: 3600 + 180 = 3780
Step 22: 3780 + 180 = 3960
Step 23: 3960 + 180 = 4140
Step 24: 4140 + 180 = 4320

So, 180*24 = 4320
