Sure thing, let's get straight to it. We start with 803 and we're going to multiply it by 6, which means adding 803 to itself 6 times.
Step 1: 0 + 803 = 803
Step 2: 803 + 803 = 1606
Step 3: 1606 + 803 = 2409
Step 4: 2409 + 803 = 3212
Step 5: 3212 + 803 = 4015
Step 6: 4015 + 803 = 4818

So, 803*6 = 4818
