$Cau1\left(27-514\right)-\left(486-78\right)$

$=\left(-487\right)-408$

$=-895$

$Cau2:\left(65-100\right)-\left(25-100\right)$

$=-35-\left(-75\right)$

$=40$

$Cau3:\left(567-67\right)-\left(56+4+33\right)$

$=500-\left(60+33\right)$

$=500-93$

$=407$Câu trả lời: $Cau1\left(27-514\right)-\left(486-78\right)$
