Without delay, let's solve this. We've got 777 and we will be multiplying it by 22, that is, adding 777 to itself 22 times.
Step 1: 0 + 777 = 777
Step 2: 777 + 777 = 1554
Step 3: 1554 + 777 = 2331
Step 4: 2331 + 777 = 3108
Step 5: 3108 + 777 = 3885
Step 6: 3885 + 777 = 4662
Step 7: 4662 + 777 = 5439
Step 8: 5439 + 777 = 6216
Step 9: 6216 + 777 = 6993
Step 10: 6993 + 777 = 7770
Step 11: 7770 + 777 = 8547
Step 12: 8547 + 777 = 9324
Step 13: 9324 + 777 = 10101
Step 14: 10101 + 777 = 10878
Step 15: 10878 + 777 = 11655
Step 16: 11655 + 777 = 12432
Step 17: 12432 + 777 = 13209
Step 18: 13209 + 777 = 13986
Step 19: 13986 + 777 = 14763
Step 20: 14763 + 777 = 15540
Step 21: 15540 + 777 = 16317
Step 22: 16317 + 777 = 17094

So, 777*22 = 17094
