Alright, let's solve this math problem step by step. First, we have the number 816. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 8. So, we're going to take the number 816 and add it to itself 8 times.
Step 1: 0 + 816 = 816
Step 2: 816 + 816 = 1632
Step 3: 1632 + 816 = 2448
Step 4: 2448 + 816 = 3264
Step 5: 3264 + 816 = 4080
Step 6: 4080 + 816 = 4896
Step 7: 4896 + 816 = 5712
Step 8: 5712 + 816 = 6528

So, 816*8 = 6528
