Alright, let's solve this math problem step by step. First, we have the number 531. 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 531 and add it to itself 26 times.
Step 1: 0 + 531 = 531
Step 2: 531 + 531 = 1062
Step 3: 1062 + 531 = 1593
Step 4: 1593 + 531 = 2124
Step 5: 2124 + 531 = 2655
Step 6: 2655 + 531 = 3186
Step 7: 3186 + 531 = 3717
Step 8: 3717 + 531 = 4248
Step 9: 4248 + 531 = 4779
Step 10: 4779 + 531 = 5310
Step 11: 5310 + 531 = 5841
Step 12: 5841 + 531 = 6372
Step 13: 6372 + 531 = 6903
Step 14: 6903 + 531 = 7434
Step 15: 7434 + 531 = 7965
Step 16: 7965 + 531 = 8496
Step 17: 8496 + 531 = 9027
Step 18: 9027 + 531 = 9558
Step 19: 9558 + 531 = 10089
Step 20: 10089 + 531 = 10620
Step 21: 10620 + 531 = 11151
Step 22: 11151 + 531 = 11682
Step 23: 11682 + 531 = 12213
Step 24: 12213 + 531 = 12744
Step 25: 12744 + 531 = 13275
Step 26: 13275 + 531 = 13806

So, 531*26 = 13806
