Let's roll up our sleeves and solve this. We have 693 and we're going to multiply it by 6, essentially adding 693 to itself 6 times.
Step 1: 0 + 693 = 693
Step 2: 693 + 693 = 1386
Step 3: 1386 + 693 = 2079
Step 4: 2079 + 693 = 2772
Step 5: 2772 + 693 = 3465
Step 6: 3465 + 693 = 4158

So, 693*6 = 4158
