Answer 1

888×4+444×12
观察题目可发现，888是444的倍数，12是4的倍数，简便方法不止一种，下面2种为例，请作参考
888×4+444×12
=888×4+444×2×6
=888×4+888×6
=888×(4+6)
=888×10
=8880

888×4+444×12
=444×2×4+444×12
=444×(8+12)
=444×20
=8880

Answer 2

先观察888与444很像，可以把它们变成相同的数，就有公因数可提取了
方法1
888x4+444x12
=888x4+444x2X6
=888x4+888X6
=888X(4+6)
=888X10
=8880
方法2
888x4+444X12
=444X2ⅹ4+444x12
=444x8+444X12
=444X(8+12)
=444x20
=8880

Answer 3

888*4+444*12
=888*4+888*6
=888*（4+6）
=888*10
=8880

Answer 4

原式=888Ⅹ4+444×2×6
=888×4+888×6
=888×（4+6）
=888×10
=8880

Answer 5

888×4+444×12

=444×2×4+444×12
=444×（2×4+12）
=444×20
