=（999+667X3）X111
=3000X111
=333000

Answer 2

999*111+333*667= 333*3*111+333*667=333*(333+667)= 333000

Answer 3

999×111+333×667
=333×333+333×667
=333×(333+667)
=333×1000
=333000

Answer 4

999×111+333×667
=333×333+333×667
=333×（333+667）
=333×1000
=333000

Answer 5

原式=333x3x111+333x667
=333x333+333x667
=333x(333+667)
=333x1000
=333000
