OK, let's crack this. We're given 822 and our task is to multiply it by 7. Essentially, we'll be adding 822 to itself 7 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

So, 822*7 = 5754
