Sure thing! We've got 335 and we're gonna multiply it by 9. That's the same as adding 335 to itself 9 times.
Step 1: 0 + 335 = 335
Step 2: 335 + 335 = 670
Step 3: 670 + 335 = 1005
Step 4: 1005 + 335 = 1340
Step 5: 1340 + 335 = 1675
Step 6: 1675 + 335 = 2010
Step 7: 2010 + 335 = 2345
Step 8: 2345 + 335 = 2680
Step 9: 2680 + 335 = 3015

So, 335*9 = 3015
