Step 7: 4968 + 828 = 5796
Step 8: 5796 + 828 = 6624
Step 9: 6624 + 828 = 7452
Step 10: 7452 + 828 = 8280
Step 11: 8280 + 828 = 9108
Step 12: 9108 + 828 = 9936
Step 13: 9936 + 828 = 10764
Step 14: 10764 + 828 = 11592
Step 15: 11592 + 828 = 12420
Step 16: 12420 + 828 = 13248
Step 17: 13248 + 828 = 14076
Step 18: 14076 + 828 = 14904
Step 19: 14904 + 828 = 15732
Step 20: 15732 + 828 = 16560
Step 21: 16560 + 828 = 17388
Step 22: 17388 + 828 = 18216
Step 23: 18216 + 828 = 19044
Step 24: 19044 + 828 = 19872
Step 25: 19872 + 828 = 20700
Step 26: 20700 + 828 = 21528
Step 27: 21528 + 828 = 22356
Step 28: 22356 + 828 = 23184
Step 29: 23184 + 828 = 24012
Step 30: 24012 + 828 = 24840
Step 31: 24840 + 828 = 25668
Step 32: 25668 + 828 = 26496
Step 33: 26496 + 828 = 27324
Step 34: 27324 + 828 = 28152
Step 35: 28152 + 828 = 28980
Step 36: 28980 + 828 = 29808
Step 37: 29808 + 828 = 30636
Step 38: 30636 + 828 = 31464
Step 39: 31464 + 828 = 32292
Step 40: 32292 + 828 = 33120

So, 828*40 = 33120
