Sure thing, let's get straight to it. We start with 979 and we're going to multiply it by 25, which means adding 979 to itself 25 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
Step 16: 14685 + 979 = 15664
Step 17: 15664 + 979 = 16643
Step 18: 16643 + 979 = 17622
Step 19: 17622 + 979 = 18601
Step 20: 18601 + 979 = 19580
Step 21: 19580 + 979 = 20559
Step 22: 20559 + 979 = 21538
Step 23: 21538 + 979 = 22517
Step 24: 22517 + 979 = 23496
Step 25: 23496 + 979 = 24475

So, 979*25 = 24475
