Alright, let's solve this math problem step by step. First, we have the number 109. 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 109 and add it to itself 9 times.
Step 1: 0 + 109 = 109
Step 2: 109 + 109 = 218
Step 3: 218 + 109 = 327
Step 4: 327 + 109 = 436
Step 5: 436 + 109 = 545
Step 6: 545 + 109 = 654
Step 7: 654 + 109 = 763
Step 8: 763 + 109 = 872
Step 9: 872 + 109 = 981

So, 109*9 = 981
