Question

36✘45-35✘46有几种简便计算方法？

Answer 1

36x45-35X46
=(35十1)X45-35X(45十1)
=35X45十45一35X45一35
=45一35
=10。

Answer 2

①36x45-35x46
=(35+1)x45-35x(45+1)
=35x45+45-35x45-35
=45-35
=10
②36×45-35×46
=36×(46-1)-(36-1)x46
=36x46-36-36x46+46
=10
③36×45-35×46
=36×45-(36-1)x(45+1)
=36x45-(36x45-45+36–1)
=36x45-36x45+45-36+1
=10
④36×45-35x46
=(35+1)x(46-1)-35x46
=35x46-35+46-1-35x46
=46-36
=10

Answer 3

36x45-35X46

=(35十1)X45-35X(45十1)

=（35X45十45）一（35X45+35
）
=45一35

=10。

Answer 4

36*45-35*46
=9*2*2*5*9-7*5*2*23
=(2*5)*(9*9*2-7*23)
=10*(81*2-161)
=10*(162-161)
=10

36*45-35*46
=(35+1)*45-35*(45+1)
=35*45+45-35*45-35
=(35*45-35*45)+(45-35)
=10

36*45-35*46
=36*(46-1)-(36-1)*46
=36*46-36-36*46+46
=(46-36)+(36*46-36*46)
=10
