OK, let's work through this together. We're starting with 71 and we're going to multiply it by 17, which means we add 71 to itself 17 times.
Step 1: 0 + 71 = 71
Step 2: 71 + 71 = 142
Step 3: 142 + 71 = 213
Step 4: 213 + 71 = 284
Step 5: 284 + 71 = 355
Step 6: 355 + 71 = 426
Step 7: 426 + 71 = 497
Step 8: 497 + 71 = 568
Step 9: 568 + 71 = 639
Step 10: 639 + 71 = 710
Step 11: 710 + 71 = 781
Step 12: 781 + 71 = 852
Step 13: 852 + 71 = 923
Step 14: 923 + 71 = 994
Step 15: 994 + 71 = 1065
Step 16: 1065 + 71 = 1136
Step 17: 1136 + 71 = 1207

So, 71*17 = 1207
