Sure thing! We've got 324 and we're gonna multiply it by 8. That's the same as adding 324 to itself 8 times.
Step 1: 0 + 324 = 324
Step 2: 324 + 324 = 648
Step 3: 648 + 324 = 972
Step 4: 972 + 324 = 1296
Step 5: 1296 + 324 = 1620
Step 6: 1620 + 324 = 1944
Step 7: 1944 + 324 = 2268
Step 8: 2268 + 324 = 2592

So, 324*8 = 2592
