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 11. So, we're going to take the number 431 and add it to itself 11 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

So, 431*11 = 4741
