Alright, let's solve this math problem step by step. First, we have the number 557. 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 557 and add it to itself 26 times.
Step 1: 0 + 557 = 557
Step 2: 557 + 557 = 1114
Step 3: 1114 + 557 = 1671
Step 4: 1671 + 557 = 2228
Step 5: 2228 + 557 = 2785
Step 6: 2785 + 557 = 3342
Step 7: 3342 + 557 = 3899
Step 8: 3899 + 557 = 4456
Step 9: 4456 + 557 = 5013
Step 10: 5013 + 557 = 5570
Step 11: 5570 + 557 = 6127
Step 12: 6127 + 557 = 6684
Step 13: 6684 + 557 = 7241
Step 14: 7241 + 557 = 7798
Step 15: 7798 + 557 = 8355
Step 16: 8355 + 557 = 8912
Step 17: 8912 + 557 = 9469
Step 18: 9469 + 557 = 10026
Step 19: 10026 + 557 = 10583
Step 20: 10583 + 557 = 11140
Step 21: 11140 + 557 = 11697
Step 22: 11697 + 557 = 12254
Step 23: 12254 + 557 = 12811
Step 24: 12811 + 557 = 13368
Step 25: 13368 + 557 = 13925
Step 26: 13925 + 557 = 14482

So, 557*26 = 14482
