Alright, let's solve this math problem step by step. First, we have the number 986. 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 986 and add it to itself 13 times.
Step 1: 0 + 986 = 986
Step 2: 986 + 986 = 1972
Step 3: 1972 + 986 = 2958
Step 4: 2958 + 986 = 3944
Step 5: 3944 + 986 = 4930
Step 6: 4930 + 986 = 5916
Step 7: 5916 + 986 = 6902
Step 8: 6902 + 986 = 7888
Step 9: 7888 + 986 = 8874
Step 10: 8874 + 986 = 9860
Step 11: 9860 + 986 = 10846
Step 12: 10846 + 986 = 11832
Step 13: 11832 + 986 = 12818

So, 986*13 = 12818
