Sure thing! We've got 787 and we're gonna multiply it by 8. That's the same as adding 787 to itself 8 times.
Step 1: 0 + 787 = 787
Step 2: 787 + 787 = 1574
Step 3: 1574 + 787 = 2361
Step 4: 2361 + 787 = 3148
Step 5: 3148 + 787 = 3935
Step 6: 3935 + 787 = 4722
Step 7: 4722 + 787 = 5509
Step 8: 5509 + 787 = 6296

So, 787*8 = 6296
