Answer 1

方法1
333×(3×222+334’
=333×(666+334)
=333×1000
=333000
方法2
999×222+333×334
=（1000-1）×222+333×(1+333)
=222000-222+333+333×3×111
=222000+111×(1+999)
=222000+111000
=333000

Answer 2

Answer 3

999X222十333X334
=（1000-1）X222+333X（333+1）
=222X1000-222+333X333+333
=111X2000+111X999+111
=111X（2000+999）+111
=111X2999+111
=111X（2999+1）
=111X3000
=333000

999X222十333X334
=333X3X222+333X334
=333X(666+334)
=333X1000
=333000

Answer 4

原式=333*333*2+333*（333+1）
=333*333*2+333*333+333
=333*333*（2+1）+333
=333*999+333
=333*（999+1）
=333*1000
=333000
