Sure thing, let's get straight to it. We start with 17 and we're going to multiply it by 13, which means adding 17 to itself 13 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
Step 13: 204 + 17 = 221

So, 17*13 = 221
