(一0.125)x(一22)一(一0.125)x(一2)
=0.125x22-0.125x2
=0.125x(22-2)
=0.125x20
=2.5
=0.125x22-0.125x2
=0.125x(22-2)
=0.125x20
=2.5

(-0.125)x(-22)-(-0.125)x(-2)
=(-0.125)x[(-22)-(-2)]
=(-0.125)x(-20)
=2.5
=(-0.125)x[(-22)-(-2)]
=(-0.125)x(-20)
=2.5

(一0.125)x(一22)一(一0.125)x(一2)
=0.125×22-0.125×2
=1/8×(22-2)
=1/8×20
=2.5
=0.125×22-0.125×2
=1/8×(22-2)
=1/8×20
=2.5
