OK, let's crack this. We're given 247 and our task is to multiply it by 40. Essentially, we'll be adding 247 to itself 40 times.
Step 1: 0 + 247 = 247
Step 2: 247 + 247 = 494
Step 3: 494 + 247 = 741
Step 4: 741 + 247 = 988
Step 5: 988 + 247 = 1235
Step 6: 1235 + 247 = 1482
Step 7: 1482 + 247 = 1729
Step 8: 1729 + 247 = 1976
Step 9: 1976 + 247 = 2223
Step 10: 2223 + 247 = 2470
Step 11: 2470 + 247 = 2717
Step 12: 2717 + 247 = 2964
Step 13: 2964 + 247 = 3211
Step 14: 3211 + 247 = 3458
Step 15: 3458 + 247 = 3705
Step 16: 3705 + 247 = 3952
Step 17: 3952 + 247 = 4199
Step 18: 4199 + 247 = 4446
Step 19: 4446 + 247 = 4693
Step 20: 4693 + 247 = 4940
Step 21: 4940 + 247 = 5187
Step 22: 5187 + 247 = 5434
Step 23: 5434 + 247 = 5681
Step 24: 5681 + 247 = 5928
Step 25: 5928 + 247 = 6175
Step 26: 6175 + 247 = 6422
Step 27: 6422 + 247 = 6669
Step 28: 6669 + 247 = 6916
Step 29: 6916 + 247 = 7163
Step 30: 7163 + 247 = 7410
Step 31: 7410 + 247 = 7657
Step 32: 7657 + 247 = 7904
Step 33: 7904 + 247 = 8151
Step 34: 8151 + 247 = 8398
Step 35: 8398 + 247 = 8645
Step 36: 8645 + 247 = 8892
Step 37: 8892 + 247 = 9139
Step 38: 9139 + 247 = 9386
Step 39: 9386 + 247 = 9633
Step 40: 9633 + 247 = 9880

So, 247*40 = 9880
