Alright, let's solve this math problem step by step. First, we have the number 414. 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 414 and add it to itself 20 times.
Step 1: 0 + 414 = 414
Step 2: 414 + 414 = 828
Step 3: 828 + 414 = 1242
Step 4: 1242 + 414 = 1656
Step 5: 1656 + 414 = 2070
Step 6: 2070 + 414 = 2484
Step 7: 2484 + 414 = 2898
Step 8: 2898 + 414 = 3312
Step 9: 3312 + 414 = 3726
Step 10: 3726 + 414 = 4140
Step 11: 4140 + 414 = 4554
Step 12: 4554 + 414 = 4968
Step 13: 4968 + 414 = 5382
Step 14: 5382 + 414 = 5796
Step 15: 5796 + 414 = 6210
Step 16: 6210 + 414 = 6624
Step 17: 6624 + 414 = 7038
Step 18: 7038 + 414 = 7452
Step 19: 7452 + 414 = 7866
Step 20: 7866 + 414 = 8280

So, 414*20 = 8280
