Alright, let's solve this math problem step by step. First, we have the number 86. 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 86 and add it to itself 11 times.
Step 1: 0 + 86 = 86
Step 2: 86 + 86 = 172
Step 3: 172 + 86 = 258
Step 4: 258 + 86 = 344
Step 5: 344 + 86 = 430
Step 6: 430 + 86 = 516
Step 7: 516 + 86 = 602
Step 8: 602 + 86 = 688
Step 9: 688 + 86 = 774
Step 10: 774 + 86 = 860
Step 11: 860 + 86 = 946

So, 86*11 = 946
