(+12)(-18)(-40)
---------------------<-----除線
(-36)(+5)(-48)


=(-216)x(-40)
--------------------- (註:括號間,沒有符號的話,就等於 x )
(-180)x(-48)


(+8640)
= -------------
(+8640)

8640
= + ---------
8640
=+1

公式:正正得正,正負得負,負正得負,負負得正

例:(+1) + (+1) (+1) + (-1) (+1) - (+1) (+1) - (-1)
=+1+1 =+1-1 =+1-1 =+1+1
=2 =0 =0 =2

(+12)(-18)(-40) / (-36)(+5)(-48)
= 8640 / 8640
= 1

(+12)(-18)(-40)
---------------------
(-36)(+5)(-48)

=+12-18-40/-36+5-48
= -6/-17

---------------------<-----除線
(-36)(+5)(-48)



=(-216)(-40)÷(-180)(-48)

=8640÷8640

=1
