Without delay, let's solve this. We've got 716 and we will be multiplying it by 20, that is, adding 716 to itself 20 times.
Step 1: 0 + 716 = 716
Step 2: 716 + 716 = 1432
Step 3: 1432 + 716 = 2148
Step 4: 2148 + 716 = 2864
Step 5: 2864 + 716 = 3580
Step 6: 3580 + 716 = 4296
Step 7: 4296 + 716 = 5012
Step 8: 5012 + 716 = 5728
Step 9: 5728 + 716 = 6444
Step 10: 6444 + 716 = 7160
Step 11: 7160 + 716 = 7876
Step 12: 7876 + 716 = 8592
Step 13: 8592 + 716 = 9308
Step 14: 9308 + 716 = 10024
Step 15: 10024 + 716 = 10740
Step 16: 10740 + 716 = 11456
Step 17: 11456 + 716 = 12172
Step 18: 12172 + 716 = 12888
Step 19: 12888 + 716 = 13604
Step 20: 13604 + 716 = 14320

So, 716*20 = 14320
