Alright, let's solve this math problem step by step. First, we have the number 516. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 26. So, we're going to take the number 516 and add it to itself 26 times.
Step 1: 0 + 516 = 516
Step 2: 516 + 516 = 1032
Step 3: 1032 + 516 = 1548
Step 4: 1548 + 516 = 2064
Step 5: 2064 + 516 = 2580
Step 6: 2580 + 516 = 3096
Step 7: 3096 + 516 = 3612
Step 8: 3612 + 516 = 4128
Step 9: 4128 + 516 = 4644
Step 10: 4644 + 516 = 5160
Step 11: 5160 + 516 = 5676
Step 12: 5676 + 516 = 6192
Step 13: 6192 + 516 = 6708
Step 14: 6708 + 516 = 7224
Step 15: 7224 + 516 = 7740
Step 16: 7740 + 516 = 8256
Step 17: 8256 + 516 = 8772
Step 18: 8772 + 516 = 9288
Step 19: 9288 + 516 = 9804
Step 20: 9804 + 516 = 10320
Step 21: 10320 + 516 = 10836
Step 22: 10836 + 516 = 11352
Step 23: 11352 + 516 = 11868
Step 24: 11868 + 516 = 12384
Step 25: 12384 + 516 = 12900
Step 26: 12900 + 516 = 13416

So, 516*26 = 13416
