Alright, let's solve this math problem step by step. First, we have the number 412. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 18. So, we're going to take the number 412 and add it to itself 18 times.
Step 1: 0 + 412 = 412
Step 2: 412 + 412 = 824
Step 3: 824 + 412 = 1236
Step 4: 1236 + 412 = 1648
Step 5: 1648 + 412 = 2060
Step 6: 2060 + 412 = 2472
Step 7: 2472 + 412 = 2884
Step 8: 2884 + 412 = 3296
Step 9: 3296 + 412 = 3708
Step 10: 3708 + 412 = 4120
Step 11: 4120 + 412 = 4532
Step 12: 4532 + 412 = 4944
Step 13: 4944 + 412 = 5356
Step 14: 5356 + 412 = 5768
Step 15: 5768 + 412 = 6180
Step 16: 6180 + 412 = 6592
Step 17: 6592 + 412 = 7004
Step 18: 7004 + 412 = 7416

So, 412*18 = 7416
