Alright, let's solve this math problem step by step. First, we have the number 207. 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 207 and add it to itself 12 times.
Step 1: 0 + 207 = 207
Step 2: 207 + 207 = 414
Step 3: 414 + 207 = 621
Step 4: 621 + 207 = 828
Step 5: 828 + 207 = 1035
Step 6: 1035 + 207 = 1242
Step 7: 1242 + 207 = 1449
Step 8: 1449 + 207 = 1656
Step 9: 1656 + 207 = 1863
Step 10: 1863 + 207 = 2070
Step 11: 2070 + 207 = 2277
Step 12: 2277 + 207 = 2484

So, 207*12 = 2484
