Alright, let's solve this math problem step by step. First, we have the number 55. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 9. So, we're going to take the number 55 and add it to itself 9 times.
Step 1: 0 + 55 = 55
Step 2: 55 + 55 = 110
Step 3: 110 + 55 = 165
Step 4: 165 + 55 = 220
Step 5: 220 + 55 = 275
Step 6: 275 + 55 = 330
Step 7: 330 + 55 = 385
Step 8: 385 + 55 = 440
Step 9: 440 + 55 = 495

So, 55*9 = 495
