Without delay, let's solve this. We've got 249 and we will be multiplying it by 27, that is, adding 249 to itself 27 times.
Step 1: 0 + 249 = 249
Step 2: 249 + 249 = 498
Step 3: 498 + 249 = 747
Step 4: 747 + 249 = 996
Step 5: 996 + 249 = 1245
Step 6: 1245 + 249 = 1494
Step 7: 1494 + 249 = 1743
Step 8: 1743 + 249 = 1992
Step 9: 1992 + 249 = 2241
Step 10: 2241 + 249 = 2490
Step 11: 2490 + 249 = 2739
Step 12: 2739 + 249 = 2988
Step 13: 2988 + 249 = 3237
Step 14: 3237 + 249 = 3486
Step 15: 3486 + 249 = 3735
Step 16: 3735 + 249 = 3984
Step 17: 3984 + 249 = 4233
Step 18: 4233 + 249 = 4482
Step 19: 4482 + 249 = 4731
Step 20: 4731 + 249 = 4980
Step 21: 4980 + 249 = 5229
Step 22: 5229 + 249 = 5478
Step 23: 5478 + 249 = 5727
Step 24: 5727 + 249 = 5976
Step 25: 5976 + 249 = 6225
Step 26: 6225 + 249 = 6474
Step 27: 6474 + 249 = 6723

So, 249*27 = 6723
