用简便方法计算 165乘以122加24乘以122加2乘以122减191乘以122
用简便方法计算 165乘以122加24乘以122加2乘以122减191乘以22

165X122+24X122+2X122-191X122
=122X(165+24+2-191)
=122X(191-191)
=122X0
=0
165X122+24X122+2X122-191X122
= 122X(165+24+2)-191X22
=122X191-191X22
=191X(122-22)
=191X100
=19100
16X122+24X122+2X122-191X22
=122X(16+24+2)-191X22
=122X42-191X22
=122X22+122X20-191X22
=22X(122-191)+122X20
=22X69+122X20
=69X20+69X2+122X20
=20X(69+122)+69X2
=20X191+6.9X20
=20X(191+6.9)
=20X197.9
=2X1979
=3958
