OK, let's work through this together. We're starting with 824 and we're going to multiply it by 7, which means we add 824 to itself 7 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

So, 824*7 = 5768
