Alright, let's solve this math problem step by step. First, we have the number 782. 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 782 and add it to itself 13 times.
Step 1: 0 + 782 = 782
Step 2: 782 + 782 = 1564
Step 3: 1564 + 782 = 2346
Step 4: 2346 + 782 = 3128
Step 5: 3128 + 782 = 3910
Step 6: 3910 + 782 = 4692
Step 7: 4692 + 782 = 5474
Step 8: 5474 + 782 = 6256
Step 9: 6256 + 782 = 7038
Step 10: 7038 + 782 = 7820
Step 11: 7820 + 782 = 8602
Step 12: 8602 + 782 = 9384
Step 13: 9384 + 782 = 10166

So, 782*13 = 10166
