Question

333乘9加111乘73的简便方法？

Answer 1

解析如下：
333×9+111×73
=111×3×9+111×73
=111×27+111×73
=111×(27+73)
=111×100
=11100

Answer 2

乘法分配律为：两个数的和与一个数相乘，先将它们与这个数分别相乘，再相加，积不变．即：（a+b）×c=a×c+b×c．反过来则：a×c+b×c=（a+b）×c
333×9+111×73
= 3× 111×9+111× 73
= 111× ( 3×9 +73)
= 111× 100
= 11,100

Answer 3

333x9+111x73
=3x111x9+111x73
=111x(3x9+73)
=111x(27+73)
=111x100
=11100

Answer 4

=111×(3×9)+111×73
=111×(27+73)
=11100
