Sure thing! We've got 958 and we're gonna multiply it by 13. That's the same as adding 958 to itself 13 times.
Step 1: 0 + 958 = 958
Step 2: 958 + 958 = 1916
Step 3: 1916 + 958 = 2874
Step 4: 2874 + 958 = 3832
Step 5: 3832 + 958 = 4790
Step 6: 4790 + 958 = 5748
Step 7: 5748 + 958 = 6706
Step 8: 6706 + 958 = 7664
Step 9: 7664 + 958 = 8622
Step 10: 8622 + 958 = 9580
Step 11: 9580 + 958 = 10538
Step 12: 10538 + 958 = 11496
Step 13: 11496 + 958 = 12454

So, 958*13 = 12454
