Alright, let's solve this math problem step by step. First, we have the number 54. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 40. So, we're going to take the number 54 and add it to itself 40 times.
Step 1: 0 + 54 = 54
Step 2: 54 + 54 = 108
Step 3: 108 + 54 = 162
Step 4: 162 + 54 = 216
Step 5: 216 + 54 = 270
Step 6: 270 + 54 = 324
Step 7: 324 + 54 = 378
Step 8: 378 + 54 = 432
Step 9: 432 + 54 = 486
Step 10: 486 + 54 = 540
Step 11: 540 + 54 = 594
Step 12: 594 + 54 = 648
Step 13: 648 + 54 = 702
Step 14: 702 + 54 = 756
Step 15: 756 + 54 = 810
Step 16: 810 + 54 = 864
Step 17: 864 + 54 = 918
Step 18: 918 + 54 = 972
Step 19: 972 + 54 = 1026
Step 20: 1026 + 54 = 1080
Step 21: 1080 + 54 = 1134
Step 22: 1134 + 54 = 1188
Step 23: 1188 + 54 = 1242
Step 24: 1242 + 54 = 1296
Step 25: 1296 + 54 = 1350
Step 26: 1350 + 54 = 1404
Step 27: 1404 + 54 = 1458
Step 28: 1458 + 54 = 1512
Step 29: 1512 + 54 = 1566
Step 30: 1566 + 54 = 1620
Step 31: 1620 + 54 = 1674
Step 32: 1674 + 54 = 1728
Step 33: 1728 + 54 = 1782
Step 34: 1782 + 54 = 1836
Step 35: 1836 + 54 = 1890
Step 36: 1890 + 54 = 1944
Step 37: 1944 + 54 = 1998
Step 38: 1998 + 54 = 2052
Step 39: 2052 + 54 = 2106
Step 40: 2106 + 54 = 2160

So, 54*40 = 2160
