Sure thing! We've got 78 and we're gonna multiply it by 22. That's the same as adding 78 to itself 22 times.
Step 1: 0 + 78 = 78
Step 2: 78 + 78 = 156
Step 3: 156 + 78 = 234
Step 4: 234 + 78 = 312
Step 5: 312 + 78 = 390
Step 6: 390 + 78 = 468
Step 7: 468 + 78 = 546
Step 8: 546 + 78 = 624
Step 9: 624 + 78 = 702
Step 10: 702 + 78 = 780
Step 11: 780 + 78 = 858
Step 12: 858 + 78 = 936
Step 13: 936 + 78 = 1014
Step 14: 1014 + 78 = 1092
Step 15: 1092 + 78 = 1170
Step 16: 1170 + 78 = 1248
Step 17: 1248 + 78 = 1326
Step 18: 1326 + 78 = 1404
Step 19: 1404 + 78 = 1482
Step 20: 1482 + 78 = 1560
Step 21: 1560 + 78 = 1638
Step 22: 1638 + 78 = 1716

So, 78*22 = 1716
