Alright, let's solve this math problem step by step. First, we have the number 338. 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 338 and add it to itself 12 times.
Step 1: 0 + 338 = 338
Step 2: 338 + 338 = 676
Step 3: 676 + 338 = 1014
Step 4: 1014 + 338 = 1352
Step 5: 1352 + 338 = 1690
Step 6: 1690 + 338 = 2028
Step 7: 2028 + 338 = 2366
Step 8: 2366 + 338 = 2704
Step 9: 2704 + 338 = 3042
Step 10: 3042 + 338 = 3380
Step 11: 3380 + 338 = 3718
Step 12: 3718 + 338 = 4056

So, 338*12 = 4056
