OK, let's crack this. We're given 180 and our task is to multiply it by 11. Essentially, we'll be adding 180 to itself 11 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

So, 180*11 = 1980
