Let's get this math done. We have 742 and we're going to multiply it by 22. This is the same as taking 742 and adding it to itself 22 times.
Step 1: 0 + 742 = 742
Step 2: 742 + 742 = 1484
Step 3: 1484 + 742 = 2226
Step 4: 2226 + 742 = 2968
Step 5: 2968 + 742 = 3710
Step 6: 3710 + 742 = 4452
Step 7: 4452 + 742 = 5194
Step 8: 5194 + 742 = 5936
Step 9: 5936 + 742 = 6678
Step 10: 6678 + 742 = 7420
Step 11: 7420 + 742 = 8162
Step 12: 8162 + 742 = 8904
Step 13: 8904 + 742 = 9646
Step 14: 9646 + 742 = 10388
Step 15: 10388 + 742 = 11130
Step 16: 11130 + 742 = 11872
Step 17: 11872 + 742 = 12614
Step 18: 12614 + 742 = 13356
Step 19: 13356 + 742 = 14098
Step 20: 14098 + 742 = 14840
Step 21: 14840 + 742 = 15582
Step 22: 15582 + 742 = 16324

So, 742*22 = 16324
