Alright, let's solve this math problem step by step. First, we have the number 126. 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 126 and add it to itself 11 times.
Step 1: 0 + 126 = 126
Step 2: 126 + 126 = 252
Step 3: 252 + 126 = 378
Step 4: 378 + 126 = 504
Step 5: 504 + 126 = 630
Step 6: 630 + 126 = 756
Step 7: 756 + 126 = 882
Step 8: 882 + 126 = 1008
Step 9: 1008 + 126 = 1134
Step 10: 1134 + 126 = 1260
Step 11: 1260 + 126 = 1386

So, 126*11 = 1386
