谁能帮我详细解答一下这道小学六年级的数学题 9999乘以2222+3333乘以3334
怎么算的公式？要细节的公式？

Answer 1

设a=1111，盯如洞橡灶则原式凯枯=9a*2a+3a(3a+1)=18a2+9a2+3a=3a(6a+3a+1)=3a(9a+1)=3333(9999+1)=333300000

Answer 2

3333乘槐信以(2222×3333)+3333乘以旅腊3334
=3333×（6666+3334）拆明滑
=3333×10000
=33330000

Answer 3

9999*2222+3333*3334 =（9999/3）*（裤铅纯2222*3）+3333*3334
=3333*（激拿6666+3334）胡咐
=3333*10000
=33330000

Answer 4

(10000-1)*(5000+500+50+5)*(3000+300+30+4)
分开来裤厅算，乘法分配律，再不行亏纯磨，销斗用计算器

Answer 5

9999X2222+3333X3334
=(10000—1)X2222+3333X(3333+1)
=(2222X10000—圆歼迅橘此2222)+(3333X3333+3333)
=2222X10000—改铅2222+3333X3333+3333
=2222X10000+3333X3333+1111
=1111(2X10000+3X3333+1)
=1111X30000=33330000
