Alright, let's solve this math problem step by step. First, we have the number 401. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 27. So, we're going to take the number 401 and add it to itself 27 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
Step 20: 7619 + 401 = 8020
Step 21: 8020 + 401 = 8421
Step 22: 8421 + 401 = 8822
Step 23: 8822 + 401 = 9223
Step 24: 9223 + 401 = 9624
Step 25: 9624 + 401 = 10025
Step 26: 10025 + 401 = 10426
Step 27: 10426 + 401 = 10827

So, 401*27 = 10827
