Sure thing, let's get straight to it. We start with 412 and we're going to multiply it by 26, which means adding 412 to itself 26 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
Step 19: 7416 + 412 = 7828
Step 20: 7828 + 412 = 8240
Step 21: 8240 + 412 = 8652
Step 22: 8652 + 412 = 9064
Step 23: 9064 + 412 = 9476
Step 24: 9476 + 412 = 9888
Step 25: 9888 + 412 = 10300
Step 26: 10300 + 412 = 10712

So, 412*26 = 10712
