OK, let's crack this. We're given 824 and our task is to multiply it by 10. Essentially, we'll be adding 824 to itself 10 times.
Step 1: 0 + 824 = 824
Step 2: 824 + 824 = 1648
Step 3: 1648 + 824 = 2472
Step 4: 2472 + 824 = 3296
Step 5: 3296 + 824 = 4120
Step 6: 4120 + 824 = 4944
Step 7: 4944 + 824 = 5768
Step 8: 5768 + 824 = 6592
Step 9: 6592 + 824 = 7416
Step 10: 7416 + 824 = 8240

So, 824*10 = 8240
