Sure thing! We've got 782 and we're gonna multiply it by 8. That's the same as adding 782 to itself 8 times.
Step 1: 0 + 782 = 782
Step 2: 782 + 782 = 1564
Step 3: 1564 + 782 = 2346
Step 4: 2346 + 782 = 3128
Step 5: 3128 + 782 = 3910
Step 6: 3910 + 782 = 4692
Step 7: 4692 + 782 = 5474
Step 8: 5474 + 782 = 6256

So, 782*8 = 6256
