OK, let's crack this. We're given 889 and our task is to multiply it by 7. Essentially, we'll be adding 889 to itself 7 times.
Step 1: 0 + 889 = 889
Step 2: 889 + 889 = 1778
Step 3: 1778 + 889 = 2667
Step 4: 2667 + 889 = 3556
Step 5: 3556 + 889 = 4445
Step 6: 4445 + 889 = 5334
Step 7: 5334 + 889 = 6223

So, 889*7 = 6223
