Alright, let's solve this math problem step by step. First, we have the number 654. 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 654 and add it to itself 6 times.
Step 1: 0 + 654 = 654
Step 2: 654 + 654 = 1308
Step 3: 1308 + 654 = 1962
Step 4: 1962 + 654 = 2616
Step 5: 2616 + 654 = 3270
Step 6: 3270 + 654 = 3924

So, 654*6 = 3924
