Sure thing! We've got 17 and we're gonna multiply it by 12. That's the same as adding 17 to itself 12 times.
Step 1: 0 + 17 = 17
Step 2: 17 + 17 = 34
Step 3: 34 + 17 = 51
Step 4: 51 + 17 = 68
Step 5: 68 + 17 = 85
Step 6: 85 + 17 = 102
Step 7: 102 + 17 = 119
Step 8: 119 + 17 = 136
Step 9: 136 + 17 = 153
Step 10: 153 + 17 = 170
Step 11: 170 + 17 = 187
Step 12: 187 + 17 = 204

So, 17*12 = 204
