  2. $10+10+30+40×100:20+10×20$
    $= 10 + 10 + 30 + 4000 :20 + 200$
    $=       20 + 30 + 200 + 200$
    $=           50 + 200 + 200$
    $=                 250 + 200$
    $ = 450$
    $20+10+30+90+100×90+10:2$
    $ = 30 + 30 + 90 + 9000 + 5$
    $ = 60 +90 +9000 + 5$
    $= 150 + 9000 +5$
    $= 9150 +5$ 
    $ = 9155$
