Let's get this math done. We have 354 and we're going to multiply it by 22. This is the same as taking 354 and adding it to itself 22 times.
Step 1: 0 + 354 = 354
Step 2: 354 + 354 = 708
Step 3: 708 + 354 = 1062
Step 4: 1062 + 354 = 1416
Step 5: 1416 + 354 = 1770
Step 6: 1770 + 354 = 2124
Step 7: 2124 + 354 = 2478
Step 8: 2478 + 354 = 2832
Step 9: 2832 + 354 = 3186
Step 10: 3186 + 354 = 3540
Step 11: 3540 + 354 = 3894
Step 12: 3894 + 354 = 4248
Step 13: 4248 + 354 = 4602
Step 14: 4602 + 354 = 4956
Step 15: 4956 + 354 = 5310
Step 16: 5310 + 354 = 5664
Step 17: 5664 + 354 = 6018
Step 18: 6018 + 354 = 6372
Step 19: 6372 + 354 = 6726
Step 20: 6726 + 354 = 7080
Step 21: 7080 + 354 = 7434
Step 22: 7434 + 354 = 7788

So, 354*22 = 7788
