OK, let's crack this. We're given 163 and our task is to multiply it by 7. Essentially, we'll be adding 163 to itself 7 times.
Step 1: 0 + 163 = 163
Step 2: 163 + 163 = 326
Step 3: 326 + 163 = 489
Step 4: 489 + 163 = 652
Step 5: 652 + 163 = 815
Step 6: 815 + 163 = 978
Step 7: 978 + 163 = 1141

So, 163*7 = 1141
