Answer 2

900 - 5 × 8 × 4 - 2 × 3 × 2 × 5 + 4 × 8 - 6 × 8 - 8 × 9 + 7 × 7 + 5 × 3 × 4 =

= 900 - 40 × 4 - 6 × 10 + 32 - 48 - 72 + 49 + 15 × 4 =

= 900 - 160 - 60 + 32 - 48 - 72 + 49 + 60 =

= 740 - 60 + 32 - 48 - 72 + 49 + 60 =

= 680 + 32 - 48 - 72 + 49 + 60 =  

= 712 - 48 - 72 + 49 + 60 =  

= 664 - 72 + 49 + 60 =  

= 592 + 49 + 60 =  

= 641 + 60 =

= 701
