OK, let's crack this. We're given 293 and our task is to multiply it by 12. Essentially, we'll be adding 293 to itself 12 times.
Step 1: 0 + 293 = 293
Step 2: 293 + 293 = 586
Step 3: 586 + 293 = 879
Step 4: 879 + 293 = 1172
Step 5: 1172 + 293 = 1465
Step 6: 1465 + 293 = 1758
Step 7: 1758 + 293 = 2051
Step 8: 2051 + 293 = 2344
Step 9: 2344 + 293 = 2637
Step 10: 2637 + 293 = 2930
Step 11: 2930 + 293 = 3223
Step 12: 3223 + 293 = 3516

So, 293*12 = 3516
