简便计算过程如下:
一、提取原式:98x37+73
二、计算过程:
=100x37-2x37+73
=3700-74+73
=3700-1
=3699
三、计算结果:3699
因为73=74-1=37×2-1。所以原式等于98×37+2×37-1运用乘法分配律逆运算就是有37×(98+2)-1=3700-1=3699
98x37+73=(100-2)x37十73=
3700-74+73=3700-1=3699
73=37✘2–1
98✘37+73=98✘37+2✘37-1=(98+2)✘37-1=3700-1=3699
=98×37+37×2-1
=37×(98+2)-1
=37×100-1
=3700-1
=3699
