  8. Answers: • 1) +8 to 0 is 8, and the distance from 0 to -5 is 5, for a total of 13. • 2) This problem is quite simple: just add $3 and $6 and the result is $9 • 3) -8,000 ÷+4 = -2,000. Each of Mrs. Jenson's four children will pay $2,000. Let's look at some more examples of dividing integers using the above rules • 4) The opposite of -282 is +282, so we get: +20,320 - -282 = +20,320 + +282 = +20,602 • 5) Owing $6 can be represented by -6. Thus the problem becomes:   (-6) (+4)
