Alright, let's solve this math problem step by step. First, we have the number 125. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 6. So, we're going to take the number 125 and add it to itself 6 times.
Step 1: 0 + 125 = 125
Step 2: 125 + 125 = 250
Step 3: 250 + 125 = 375
Step 4: 375 + 125 = 500
Step 5: 500 + 125 = 625
Step 6: 625 + 125 = 750

So, 125*6 = 750
