最佳解答:

其他解答:
(+12)(-18)(-40) / (-36)(+5)(-48) = 8640 / 8640 = 1|||||(+12)(-18)(-40) --------------------- (-36)(+5)(-48) =+12-18-40/-36+5-48 = -6/-17|||||(+12)(-18)(-40) ---------------------<-----除線 (-36)(+5)(-48) =(-216)(-40)÷(-180)(-48) =8640÷8640 =1 記住負負得正~~|||||(+12)(-18)(-40) --------------------- (-36)(+5)(-48) =12-18-40 --------------------- 5-36-48 =-46 --------------------- -79 =46/79|||||12*(-18)(-40) -------------------- (-36)(5)(-48) 8640 =--------------------- 8640 =1
