OK, let's work through this together. We're starting with 493 and we're going to multiply it by 30, which means we add 493 to itself 30 times.
Step 1: 0 + 493 = 493
Step 2: 493 + 493 = 986
Step 3: 986 + 493 = 1479
Step 4: 1479 + 493 = 1972
Step 5: 1972 + 493 = 2465
Step 6: 2465 + 493 = 2958
Step 7: 2958 + 493 = 3451
Step 8: 3451 + 493 = 3944
Step 9: 3944 + 493 = 4437
Step 10: 4437 + 493 = 4930
Step 11: 4930 + 493 = 5423
Step 12: 5423 + 493 = 5916
Step 13: 5916 + 493 = 6409
Step 14: 6409 + 493 = 6902
Step 15: 6902 + 493 = 7395
Step 16: 7395 + 493 = 7888
Step 17: 7888 + 493 = 8381
Step 18: 8381 + 493 = 8874
Step 19: 8874 + 493 = 9367
Step 20: 9367 + 493 = 9860
Step 21: 9860 + 493 = 10353
Step 22: 10353 + 493 = 10846
Step 23: 10846 + 493 = 11339
Step 24: 11339 + 493 = 11832
Step 25: 11832 + 493 = 12325
Step 26: 12325 + 493 = 12818
Step 27: 12818 + 493 = 13311
Step 28: 13311 + 493 = 13804
Step 29: 13804 + 493 = 14297
Step 30: 14297 + 493 = 14790

So, 493*30 = 14790
