OK, let's crack this. We're given 545 and our task is to multiply it by 22. Essentially, we'll be adding 545 to itself 22 times.
Step 1: 0 + 545 = 545
Step 2: 545 + 545 = 1090
Step 3: 1090 + 545 = 1635
Step 4: 1635 + 545 = 2180
Step 5: 2180 + 545 = 2725
Step 6: 2725 + 545 = 3270
Step 7: 3270 + 545 = 3815
Step 8: 3815 + 545 = 4360
Step 9: 4360 + 545 = 4905
Step 10: 4905 + 545 = 5450
Step 11: 5450 + 545 = 5995
Step 12: 5995 + 545 = 6540
Step 13: 6540 + 545 = 7085
Step 14: 7085 + 545 = 7630
Step 15: 7630 + 545 = 8175
Step 16: 8175 + 545 = 8720
Step 17: 8720 + 545 = 9265
Step 18: 9265 + 545 = 9810
Step 19: 9810 + 545 = 10355
Step 20: 10355 + 545 = 10900
Step 21: 10900 + 545 = 11445
Step 22: 11445 + 545 = 11990

So, 545*22 = 11990
