Let's get this math done. We have 273 and we're going to multiply it by 11. This is the same as taking 273 and adding it to itself 11 times.
Step 1: 0 + 273 = 273
Step 2: 273 + 273 = 546
Step 3: 546 + 273 = 819
Step 4: 819 + 273 = 1092
Step 5: 1092 + 273 = 1365
Step 6: 1365 + 273 = 1638
Step 7: 1638 + 273 = 1911
Step 8: 1911 + 273 = 2184
Step 9: 2184 + 273 = 2457
Step 10: 2457 + 273 = 2730
Step 11: 2730 + 273 = 3003

So, 273*11 = 3003
