    136,23+136,17- 40,36
    = 299,4 – 40,36
    = 259,04
    66,25 + 5,66 + 66,14 + 33,66
    = 71,91 + 66,14 + 33,66
    = 138,05 + 33,66
    = 171,71
    Theo mk dấu chấm là dấu phẩy.

    $136×23+136.17-40×36$
    $=136×(23+17)-40×36$
    $=136×40-40×36$
    $=40×(136-36)$
    $=40×100$
    $=4000$
    $66×25+5×66+66×14+33×66$
    $=66×(25+5+14+33)$
    $=66×(30+14+33)$
    $=66×(44+33)$
    $=66×77$
    $=5082$
