Alright, let's solve this math problem step by step. First, we have the number 153. 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 153 and add it to itself 6 times.
Step 1: 0 + 153 = 153
Step 2: 153 + 153 = 306
Step 3: 306 + 153 = 459
Step 4: 459 + 153 = 612
Step 5: 612 + 153 = 765
Step 6: 765 + 153 = 918

So, 153*6 = 918
