Let's get this math done. We have 711 and we're going to multiply it by 7. This is the same as taking 711 and adding it to itself 7 times.
Step 1: 0 + 711 = 711
Step 2: 711 + 711 = 1422
Step 3: 1422 + 711 = 2133
Step 4: 2133 + 711 = 2844
Step 5: 2844 + 711 = 3555
Step 6: 3555 + 711 = 4266
Step 7: 4266 + 711 = 4977

So, 711*7 = 4977
