Alright, let's solve this math problem step by step. First, we have the number 308. 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 308 and add it to itself 12 times.
Step 1: 0 + 308 = 308
Step 2: 308 + 308 = 616
Step 3: 616 + 308 = 924
Step 4: 924 + 308 = 1232
Step 5: 1232 + 308 = 1540
Step 6: 1540 + 308 = 1848
Step 7: 1848 + 308 = 2156
Step 8: 2156 + 308 = 2464
Step 9: 2464 + 308 = 2772
Step 10: 2772 + 308 = 3080
Step 11: 3080 + 308 = 3388
Step 12: 3388 + 308 = 3696

So, 308*12 = 3696
