Alright, let's solve this math problem step by step. First, we have the number 431. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 17. So, we're going to take the number 431 and add it to itself 17 times.
Step 1: 0 + 431 = 431
Step 2: 431 + 431 = 862
Step 3: 862 + 431 = 1293
Step 4: 1293 + 431 = 1724
Step 5: 1724 + 431 = 2155
Step 6: 2155 + 431 = 2586
Step 7: 2586 + 431 = 3017
Step 8: 3017 + 431 = 3448
Step 9: 3448 + 431 = 3879
Step 10: 3879 + 431 = 4310
Step 11: 4310 + 431 = 4741
Step 12: 4741 + 431 = 5172
Step 13: 5172 + 431 = 5603
Step 14: 5603 + 431 = 6034
Step 15: 6034 + 431 = 6465
Step 16: 6465 + 431 = 6896
Step 17: 6896 + 431 = 7327

So, 431*17 = 7327
