OK, let's crack this. We're given 752 and our task is to multiply it by 9. Essentially, we'll be adding 752 to itself 9 times.
Step 1: 0 + 752 = 752
Step 2: 752 + 752 = 1504
Step 3: 1504 + 752 = 2256
Step 4: 2256 + 752 = 3008
Step 5: 3008 + 752 = 3760
Step 6: 3760 + 752 = 4512
Step 7: 4512 + 752 = 5264
Step 8: 5264 + 752 = 6016
Step 9: 6016 + 752 = 6768

So, 752*9 = 6768
