Sure thing! We've got 768 and we're gonna multiply it by 8. That's the same as adding 768 to itself 8 times.
Step 1: 0 + 768 = 768
Step 2: 768 + 768 = 1536
Step 3: 1536 + 768 = 2304
Step 4: 2304 + 768 = 3072
Step 5: 3072 + 768 = 3840
Step 6: 3840 + 768 = 4608
Step 7: 4608 + 768 = 5376
Step 8: 5376 + 768 = 6144

So, 768*8 = 6144
