Let's get this math done. We have 311 and we're going to multiply it by 7. This is the same as taking 311 and adding it to itself 7 times.
Step 1: 0 + 311 = 311
Step 2: 311 + 311 = 622
Step 3: 622 + 311 = 933
Step 4: 933 + 311 = 1244
Step 5: 1244 + 311 = 1555
Step 6: 1555 + 311 = 1866
Step 7: 1866 + 311 = 2177

So, 311*7 = 2177
