Alright, let's solve this math problem step by step. First, we have the number 739. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 20. So, we're going to take the number 739 and add it to itself 20 times.
Step 1: 0 + 739 = 739
Step 2: 739 + 739 = 1478
Step 3: 1478 + 739 = 2217
Step 4: 2217 + 739 = 2956
Step 5: 2956 + 739 = 3695
Step 6: 3695 + 739 = 4434
Step 7: 4434 + 739 = 5173
Step 8: 5173 + 739 = 5912
Step 9: 5912 + 739 = 6651
Step 10: 6651 + 739 = 7390
Step 11: 7390 + 739 = 8129
Step 12: 8129 + 739 = 8868
Step 13: 8868 + 739 = 9607
Step 14: 9607 + 739 = 10346
Step 15: 10346 + 739 = 11085
Step 16: 11085 + 739 = 11824
Step 17: 11824 + 739 = 12563
Step 18: 12563 + 739 = 13302
Step 19: 13302 + 739 = 14041
Step 20: 14041 + 739 = 14780

So, 739*20 = 14780
