Alright, let's solve this math problem step by step. First, we have the number 673. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 10. So, we're going to take the number 673 and add it to itself 10 times.
Step 1: 0 + 673 = 673
Step 2: 673 + 673 = 1346
Step 3: 1346 + 673 = 2019
Step 4: 2019 + 673 = 2692
Step 5: 2692 + 673 = 3365
Step 6: 3365 + 673 = 4038
Step 7: 4038 + 673 = 4711
Step 8: 4711 + 673 = 5384
Step 9: 5384 + 673 = 6057
Step 10: 6057 + 673 = 6730

So, 673*10 = 6730
