32X15-26X14简便计算
32X15-26X14
=32*10+32*5-26*10-26*4
=320+160-260-104
=320-100-100-4=116
32X15-26X14
=32*10+32*5-26*10-26*4
=320+160-260-104
=320-100-100-4=116

32X15-26X14
=32×15-26(15-1)
=32×15-26×15-26
=15(32-26)-26
=15×6-26
=90-26
=64
=32×15-26(15-1)
=32×15-26×15-26
=15(32-26)-26
=15×6-26
=90-26
=64
