Alright, let's solve this math problem step by step. First, we have the number 556. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 18. So, we're going to take the number 556 and add it to itself 18 times.
Step 1: 0 + 556 = 556
Step 2: 556 + 556 = 1112
Step 3: 1112 + 556 = 1668
Step 4: 1668 + 556 = 2224
Step 5: 2224 + 556 = 2780
Step 6: 2780 + 556 = 3336
Step 7: 3336 + 556 = 3892
Step 8: 3892 + 556 = 4448
Step 9: 4448 + 556 = 5004
Step 10: 5004 + 556 = 5560
Step 11: 5560 + 556 = 6116
Step 12: 6116 + 556 = 6672
Step 13: 6672 + 556 = 7228
Step 14: 7228 + 556 = 7784
Step 15: 7784 + 556 = 8340
Step 16: 8340 + 556 = 8896
Step 17: 8896 + 556 = 9452
Step 18: 9452 + 556 = 10008

So, 556*18 = 10008
