100以内加减法数学题计算(运用口诀)

1、方法1,两位数加两位数的进位加法：口诀：加 9要减1,加8要减2,加7要减3, 加6要减4,加5要减5,加4要减6,加3要减7,加2要减8,加1要减9（注：口决中的加几都是说个位上的数）。方法2,两位数减两位数的退位减法。口决：口诀：减9要加1,减8要加2,减7 要加3,减6要加4,减5要加5,减4要加6,减3要加7,减2要加8,减1 要加9。（注：口决中的减几都是说减个位上的数）。45-35=29+ 24=72+7 =48+27 =60- 29=21 + 55=1 + 35=31-20=71 + 25=94-25=23+ 41 =20+55=43+1 =68+ 6 =57-44=97-7 =
