Sure thing, let's get straight to it. We start with 180 and we're going to multiply it by 9, which means adding 180 to itself 9 times.
Step 1: 0 + 180 = 180
Step 2: 180 + 180 = 360
Step 3: 360 + 180 = 540
Step 4: 540 + 180 = 720
Step 5: 720 + 180 = 900
Step 6: 900 + 180 = 1080
Step 7: 1080 + 180 = 1260
Step 8: 1260 + 180 = 1440
Step 9: 1440 + 180 = 1620

So, 180*9 = 1620
