Sure thing, let's get straight to it. We start with 347 and we're going to multiply it by 20, which means adding 347 to itself 20 times.
Step 1: 0 + 347 = 347
Step 2: 347 + 347 = 694
Step 3: 694 + 347 = 1041
Step 4: 1041 + 347 = 1388
Step 5: 1388 + 347 = 1735
Step 6: 1735 + 347 = 2082
Step 7: 2082 + 347 = 2429
Step 8: 2429 + 347 = 2776
Step 9: 2776 + 347 = 3123
Step 10: 3123 + 347 = 3470
Step 11: 3470 + 347 = 3817
Step 12: 3817 + 347 = 4164
Step 13: 4164 + 347 = 4511
Step 14: 4511 + 347 = 4858
Step 15: 4858 + 347 = 5205
Step 16: 5205 + 347 = 5552
Step 17: 5552 + 347 = 5899
Step 18: 5899 + 347 = 6246
Step 19: 6246 + 347 = 6593
Step 20: 6593 + 347 = 6940

So, 347*20 = 6940
