Let's roll up our sleeves and solve this. We have 710 and we're going to multiply it by 11, essentially adding 710 to itself 11 times.
Step 1: 0 + 710 = 710
Step 2: 710 + 710 = 1420
Step 3: 1420 + 710 = 2130
Step 4: 2130 + 710 = 2840
Step 5: 2840 + 710 = 3550
Step 6: 3550 + 710 = 4260
Step 7: 4260 + 710 = 4970
Step 8: 4970 + 710 = 5680
Step 9: 5680 + 710 = 6390
Step 10: 6390 + 710 = 7100
Step 11: 7100 + 710 = 7810

So, 710*11 = 7810
