OK, let's crack this. We're given 884 and our task is to multiply it by 7. Essentially, we'll be adding 884 to itself 7 times.
Step 1: 0 + 884 = 884
Step 2: 884 + 884 = 1768
Step 3: 1768 + 884 = 2652
Step 4: 2652 + 884 = 3536
Step 5: 3536 + 884 = 4420
Step 6: 4420 + 884 = 5304
Step 7: 5304 + 884 = 6188

So, 884*7 = 6188
