Sure thing! We've got 35 and we're gonna multiply it by 9. That's the same as adding 35 to itself 9 times.
Step 1: 0 + 35 = 35
Step 2: 35 + 35 = 70
Step 3: 70 + 35 = 105
Step 4: 105 + 35 = 140
Step 5: 140 + 35 = 175
Step 6: 175 + 35 = 210
Step 7: 210 + 35 = 245
Step 8: 245 + 35 = 280
Step 9: 280 + 35 = 315

So, 35*9 = 315
