OK, let's work through this together. We're starting with 735 and we're going to multiply it by 6, which means we add 735 to itself 6 times.
Step 1: 0 + 735 = 735
Step 2: 735 + 735 = 1470
Step 3: 1470 + 735 = 2205
Step 4: 2205 + 735 = 2940
Step 5: 2940 + 735 = 3675
Step 6: 3675 + 735 = 4410

So, 735*6 = 4410
