Let's roll up our sleeves and solve this. We have 706 and we're going to multiply it by 6, essentially adding 706 to itself 6 times.
Step 1: 0 + 706 = 706
Step 2: 706 + 706 = 1412
Step 3: 1412 + 706 = 2118
Step 4: 2118 + 706 = 2824
Step 5: 2824 + 706 = 3530
Step 6: 3530 + 706 = 4236

So, 706*6 = 4236
