Let's get this math done. We have 754 and we're going to multiply it by 6. This is the same as taking 754 and adding it to itself 6 times.
Step 1: 0 + 754 = 754
Step 2: 754 + 754 = 1508
Step 3: 1508 + 754 = 2262
Step 4: 2262 + 754 = 3016
Step 5: 3016 + 754 = 3770
Step 6: 3770 + 754 = 4524

So, 754*6 = 4524
