Alright, let's solve this math problem step by step. First, we have the number 319. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 13. So, we're going to take the number 319 and add it to itself 13 times.
Step 1: 0 + 319 = 319
Step 2: 319 + 319 = 638
Step 3: 638 + 319 = 957
Step 4: 957 + 319 = 1276
Step 5: 1276 + 319 = 1595
Step 6: 1595 + 319 = 1914
Step 7: 1914 + 319 = 2233
Step 8: 2233 + 319 = 2552
Step 9: 2552 + 319 = 2871
Step 10: 2871 + 319 = 3190
Step 11: 3190 + 319 = 3509
Step 12: 3509 + 319 = 3828
Step 13: 3828 + 319 = 4147

So, 319*13 = 4147
