问题描述:
(7/9+3/4-11/12)*36+13/19+18*13/19 简算
答
(7/9+3/4-11/12)*36+13/19+18*13/19
=28+27-33+13/19*(1+18)
=12+13/19*19
=12+13
=25应该是对的,请问为什么有人说答案是35.比如:(7/9+3/4-11/12)*36+13/19+18*13/19 =7/9×36+3/4×36-11/12×36+13/19×(1+18)=28+27-33+13/19×19=28+27-33+13=22+13=35 请回答,谢谢我算错了不好意思(7/9+3/4-11/12)*36+13/19+18*13/19 =7/9×36+3/4×36-11/12×36+13/19×(1+18)=28+27-33+13/19×19=28+27-33+13=22+13=35
