Let's roll up our sleeves and solve this. We have 593 and we're going to multiply it by 9, essentially adding 593 to itself 9 times.
Step 1: 0 + 593 = 593
Step 2: 593 + 593 = 1186
Step 3: 1186 + 593 = 1779
Step 4: 1779 + 593 = 2372
Step 5: 2372 + 593 = 2965
Step 6: 2965 + 593 = 3558
Step 7: 3558 + 593 = 4151
Step 8: 4151 + 593 = 4744
Step 9: 4744 + 593 = 5337

So, 593*9 = 5337
