Alright, let's solve this math problem step by step. First, we have the number 607. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 12. So, we're going to take the number 607 and add it to itself 12 times.
Step 1: 0 + 607 = 607
Step 2: 607 + 607 = 1214
Step 3: 1214 + 607 = 1821
Step 4: 1821 + 607 = 2428
Step 5: 2428 + 607 = 3035
Step 6: 3035 + 607 = 3642
Step 7: 3642 + 607 = 4249
Step 8: 4249 + 607 = 4856
Step 9: 4856 + 607 = 5463
Step 10: 5463 + 607 = 6070
Step 11: 6070 + 607 = 6677
Step 12: 6677 + 607 = 7284

So, 607*12 = 7284
