Sure thing, let's get straight to it. We start with 173 and we're going to multiply it by 7, which means adding 173 to itself 7 times.
Step 1: 0 + 173 = 173
Step 2: 173 + 173 = 346
Step 3: 346 + 173 = 519
Step 4: 519 + 173 = 692
Step 5: 692 + 173 = 865
Step 6: 865 + 173 = 1038
Step 7: 1038 + 173 = 1211

So, 173*7 = 1211
