Step 9: 4280 + 535 = 4815
Step 10: 4815 + 535 = 5350
Step 11: 5350 + 535 = 5885
Step 12: 5885 + 535 = 6420
Step 13: 6420 + 535 = 6955
Step 14: 6955 + 535 = 7490
Step 15: 7490 + 535 = 8025
Step 16: 8025 + 535 = 8560
Step 17: 8560 + 535 = 9095
Step 18: 9095 + 535 = 9630
Step 19: 9630 + 535 = 10165
Step 20: 10165 + 535 = 10700
Step 21: 10700 + 535 = 11235
Step 22: 11235 + 535 = 11770
Step 23: 11770 + 535 = 12305
Step 24: 12305 + 535 = 12840
Step 25: 12840 + 535 = 13375
Step 26: 13375 + 535 = 13910
Step 27: 13910 + 535 = 14445
Step 28: 14445 + 535 = 14980
Step 29: 14980 + 535 = 15515
Step 30: 15515 + 535 = 16050
Step 31: 16050 + 535 = 16585
Step 32: 16585 + 535 = 17120
Step 33: 17120 + 535 = 17655
Step 34: 17655 + 535 = 18190
Step 35: 18190 + 535 = 18725
Step 36: 18725 + 535 = 19260
Step 37: 19260 + 535 = 19795
Step 38: 19795 + 535 = 20330
Step 39: 20330 + 535 = 20865
Step 40: 20865 + 535 = 21400
Step 41: 21400 + 535 = 21935
Step 42: 21935 + 535 = 22470
Step 43: 22470 + 535 = 23005
Step 44: 23005 + 535 = 23540
Step 45: 23540 + 535 = 24075

So, 535*45 = 24075
