Let's roll up our sleeves and solve this. We have 908 and we're going to multiply it by 22, essentially adding 908 to itself 22 times.
Step 1: 0 + 908 = 908
Step 2: 908 + 908 = 1816
Step 3: 1816 + 908 = 2724
Step 4: 2724 + 908 = 3632
Step 5: 3632 + 908 = 4540
Step 6: 4540 + 908 = 5448
Step 7: 5448 + 908 = 6356
Step 8: 6356 + 908 = 7264
Step 9: 7264 + 908 = 8172
Step 10: 8172 + 908 = 9080
Step 11: 9080 + 908 = 9988
Step 12: 9988 + 908 = 10896
Step 13: 10896 + 908 = 11804
Step 14: 11804 + 908 = 12712
Step 15: 12712 + 908 = 13620
Step 16: 13620 + 908 = 14528
Step 17: 14528 + 908 = 15436
Step 18: 15436 + 908 = 16344
Step 19: 16344 + 908 = 17252
Step 20: 17252 + 908 = 18160
Step 21: 18160 + 908 = 19068
Step 22: 19068 + 908 = 19976

So, 908*22 = 19976
