Sure thing! We've got 160 and we're gonna multiply it by 9. That's the same as adding 160 to itself 9 times.
Step 1: 0 + 160 = 160
Step 2: 160 + 160 = 320
Step 3: 320 + 160 = 480
Step 4: 480 + 160 = 640
Step 5: 640 + 160 = 800
Step 6: 800 + 160 = 960
Step 7: 960 + 160 = 1120
Step 8: 1120 + 160 = 1280
Step 9: 1280 + 160 = 1440

So, 160*9 = 1440
