Sure thing, let's get straight to it. We start with 424 and we're going to multiply it by 8, which means adding 424 to itself 8 times.
Step 1: 0 + 424 = 424
Step 2: 424 + 424 = 848
Step 3: 848 + 424 = 1272
Step 4: 1272 + 424 = 1696
Step 5: 1696 + 424 = 2120
Step 6: 2120 + 424 = 2544
Step 7: 2544 + 424 = 2968
Step 8: 2968 + 424 = 3392

So, 424*8 = 3392
