Alright, let's solve this math problem step by step. First, we have the number 558. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 16. So, we're going to take the number 558 and add it to itself 16 times.
Step 1: 0 + 558 = 558
Step 2: 558 + 558 = 1116
Step 3: 1116 + 558 = 1674
Step 4: 1674 + 558 = 2232
Step 5: 2232 + 558 = 2790
Step 6: 2790 + 558 = 3348
Step 7: 3348 + 558 = 3906
Step 8: 3906 + 558 = 4464
Step 9: 4464 + 558 = 5022
Step 10: 5022 + 558 = 5580
Step 11: 5580 + 558 = 6138
Step 12: 6138 + 558 = 6696
Step 13: 6696 + 558 = 7254
Step 14: 7254 + 558 = 7812
Step 15: 7812 + 558 = 8370
Step 16: 8370 + 558 = 8928

So, 558*16 = 8928
