Without delay, let's solve this. We've got 401 and we will be multiplying it by 19, that is, adding 401 to itself 19 times.
Step 1: 0 + 401 = 401
Step 2: 401 + 401 = 802
Step 3: 802 + 401 = 1203
Step 4: 1203 + 401 = 1604
Step 5: 1604 + 401 = 2005
Step 6: 2005 + 401 = 2406
Step 7: 2406 + 401 = 2807
Step 8: 2807 + 401 = 3208
Step 9: 3208 + 401 = 3609
Step 10: 3609 + 401 = 4010
Step 11: 4010 + 401 = 4411
Step 12: 4411 + 401 = 4812
Step 13: 4812 + 401 = 5213
Step 14: 5213 + 401 = 5614
Step 15: 5614 + 401 = 6015
Step 16: 6015 + 401 = 6416
Step 17: 6416 + 401 = 6817
Step 18: 6817 + 401 = 7218
Step 19: 7218 + 401 = 7619

So, 401*19 = 7619
