Sure thing, let's get straight to it. We start with 355 and we're going to multiply it by 9, which means adding 355 to itself 9 times.
Step 1: 0 + 355 = 355
Step 2: 355 + 355 = 710
Step 3: 710 + 355 = 1065
Step 4: 1065 + 355 = 1420
Step 5: 1420 + 355 = 1775
Step 6: 1775 + 355 = 2130
Step 7: 2130 + 355 = 2485
Step 8: 2485 + 355 = 2840
Step 9: 2840 + 355 = 3195

So, 355*9 = 3195
