Sure thing! We've got 979 and we're gonna multiply it by 15. That's the same as adding 979 to itself 15 times.
Step 1: 0 + 979 = 979
Step 2: 979 + 979 = 1958
Step 3: 1958 + 979 = 2937
Step 4: 2937 + 979 = 3916
Step 5: 3916 + 979 = 4895
Step 6: 4895 + 979 = 5874
Step 7: 5874 + 979 = 6853
Step 8: 6853 + 979 = 7832
Step 9: 7832 + 979 = 8811
Step 10: 8811 + 979 = 9790
Step 11: 9790 + 979 = 10769
Step 12: 10769 + 979 = 11748
Step 13: 11748 + 979 = 12727
Step 14: 12727 + 979 = 13706
Step 15: 13706 + 979 = 14685

So, 979*15 = 14685
