Let's roll up our sleeves and solve this. We have 782 and we're going to multiply it by 6, essentially adding 782 to itself 6 times.
Step 1: 0 + 782 = 782
Step 2: 782 + 782 = 1564
Step 3: 1564 + 782 = 2346
Step 4: 2346 + 782 = 3128
Step 5: 3128 + 782 = 3910
Step 6: 3910 + 782 = 4692

So, 782*6 = 4692
