Alright, let's solve this math problem step by step. First, we have the number 27. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 39. So, we're going to take the number 27 and add it to itself 39 times.
Step 1: 0 + 27 = 27
Step 2: 27 + 27 = 54
Step 3: 54 + 27 = 81
Step 4: 81 + 27 = 108
Step 5: 108 + 27 = 135
Step 6: 135 + 27 = 162
Step 7: 162 + 27 = 189
Step 8: 189 + 27 = 216
Step 9: 216 + 27 = 243
Step 10: 243 + 27 = 270
Step 11: 270 + 27 = 297
Step 12: 297 + 27 = 324
Step 13: 324 + 27 = 351
Step 14: 351 + 27 = 378
Step 15: 378 + 27 = 405
Step 16: 405 + 27 = 432
Step 17: 432 + 27 = 459
Step 18: 459 + 27 = 486
Step 19: 486 + 27 = 513
Step 20: 513 + 27 = 540
Step 21: 540 + 27 = 567
Step 22: 567 + 27 = 594
Step 23: 594 + 27 = 621
Step 24: 621 + 27 = 648
Step 25: 648 + 27 = 675
Step 26: 675 + 27 = 702
Step 27: 702 + 27 = 729
Step 28: 729 + 27 = 756
Step 29: 756 + 27 = 783
Step 30: 783 + 27 = 810
Step 31: 810 + 27 = 837
Step 32: 837 + 27 = 864
Step 33: 864 + 27 = 891
Step 34: 891 + 27 = 918
Step 35: 918 + 27 = 945
Step 36: 945 + 27 = 972
Step 37: 972 + 27 = 999
Step 38: 999 + 27 = 1026
Step 39: 1026 + 27 = 1053

So, 27*39 = 1053
