Let's roll up our sleeves and solve this. We have 822 and we're going to multiply it by 8, essentially adding 822 to itself 8 times.
Step 1: 0 + 822 = 822
Step 2: 822 + 822 = 1644
Step 3: 1644 + 822 = 2466
Step 4: 2466 + 822 = 3288
Step 5: 3288 + 822 = 4110
Step 6: 4110 + 822 = 4932
Step 7: 4932 + 822 = 5754
Step 8: 5754 + 822 = 6576

So, 822*8 = 6576
