Answer 1

①25×33×4×2 
=（25×4）×（33×2）
=100×66
=6600


②156+6.2-15.6+6.2 
=（156-15.6）+（6.2+6.2）
=140.4+12.4
=152.8


③125×89×8
=125×8×89
=1000×89
=89000


④283×5+17×5
=5×（283+17）
=5×300
=1500


⑤43×102                
=43×（100+2）
=43×100+43×2
=4300+86
=4386


⑥428×78+572×78
=78×（428+572）
=78×1000
=78000


⑦9+99+999+9999          
=10-1+100-1+1000-1+1000-1
=11110-4
=11106


⑧286+879-679           
=286+（879-679）
=286+200
=486


⑨333×334+999×222
=333×334+333×666
=333×（334+666）
=333×1000
=333000
