Alright, let's solve this math problem step by step. First, we have the number 273. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 6. So, we're going to take the number 273 and add it to itself 6 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

So, 273*6 = 1638
