OK, let's work through this together. We're starting with 748 and we're going to multiply it by 22, which means we add 748 to itself 22 times.
Step 1: 0 + 748 = 748
Step 2: 748 + 748 = 1496
Step 3: 1496 + 748 = 2244
Step 4: 2244 + 748 = 2992
Step 5: 2992 + 748 = 3740
Step 6: 3740 + 748 = 4488
Step 7: 4488 + 748 = 5236
Step 8: 5236 + 748 = 5984
Step 9: 5984 + 748 = 6732
Step 10: 6732 + 748 = 7480
Step 11: 7480 + 748 = 8228
Step 12: 8228 + 748 = 8976
Step 13: 8976 + 748 = 9724
Step 14: 9724 + 748 = 10472
Step 15: 10472 + 748 = 11220
Step 16: 11220 + 748 = 11968
Step 17: 11968 + 748 = 12716
Step 18: 12716 + 748 = 13464
Step 19: 13464 + 748 = 14212
Step 20: 14212 + 748 = 14960
Step 21: 14960 + 748 = 15708
Step 22: 15708 + 748 = 16456

So, 748*22 = 16456
