OK, let's work through this together. We're starting with 559 and we're going to multiply it by 18, which means we add 559 to itself 18 times.
Step 1: 0 + 559 = 559
Step 2: 559 + 559 = 1118
Step 3: 1118 + 559 = 1677
Step 4: 1677 + 559 = 2236
Step 5: 2236 + 559 = 2795
Step 6: 2795 + 559 = 3354
Step 7: 3354 + 559 = 3913
Step 8: 3913 + 559 = 4472
Step 9: 4472 + 559 = 5031
Step 10: 5031 + 559 = 5590
Step 11: 5590 + 559 = 6149
Step 12: 6149 + 559 = 6708
Step 13: 6708 + 559 = 7267
Step 14: 7267 + 559 = 7826
Step 15: 7826 + 559 = 8385
Step 16: 8385 + 559 = 8944
Step 17: 8944 + 559 = 9503
Step 18: 9503 + 559 = 10062

So, 559*18 = 10062
