Without delay, let's solve this. We've got 412 and we will be multiplying it by 9, that is, adding 412 to itself 9 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

So, 412*9 = 3708
