Sure thing, let's get straight to it. We start with 171 and we're going to multiply it by 7, which means adding 171 to itself 7 times.
Step 1: 0 + 171 = 171
Step 2: 171 + 171 = 342
Step 3: 342 + 171 = 513
Step 4: 513 + 171 = 684
Step 5: 684 + 171 = 855
Step 6: 855 + 171 = 1026
Step 7: 1026 + 171 = 1197

So, 171*7 = 1197
