Let's get this math done. We have 175 and we're going to multiply it by 9. This is the same as taking 175 and adding it to itself 9 times.
Step 1: 0 + 175 = 175
Step 2: 175 + 175 = 350
Step 3: 350 + 175 = 525
Step 4: 525 + 175 = 700
Step 5: 700 + 175 = 875
Step 6: 875 + 175 = 1050
Step 7: 1050 + 175 = 1225
Step 8: 1225 + 175 = 1400
Step 9: 1400 + 175 = 1575

So, 175*9 = 1575
