Alright, let's solve this math problem step by step. First, we have the number 309. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 14. So, we're going to take the number 309 and add it to itself 14 times.
Step 1: 0 + 309 = 309
Step 2: 309 + 309 = 618
Step 3: 618 + 309 = 927
Step 4: 927 + 309 = 1236
Step 5: 1236 + 309 = 1545
Step 6: 1545 + 309 = 1854
Step 7: 1854 + 309 = 2163
Step 8: 2163 + 309 = 2472
Step 9: 2472 + 309 = 2781
Step 10: 2781 + 309 = 3090
Step 11: 3090 + 309 = 3399
Step 12: 3399 + 309 = 3708
Step 13: 3708 + 309 = 4017
Step 14: 4017 + 309 = 4326

So, 309*14 = 4326
