Answer 1

Resposta:

$\left(-3\right)-\left(-1\right)=-3+1=-2$

$47-(-47) = 94$

$0-\left(-1\right)=1$

$0-53=-53$

$\left(-14\right)-14=-28$

$\left(-63\right)-64=-127$

$\left(-36\right)-\left(-36\right)=0$

$118-\left(-102\right)=220$

$\left(-17\right)-\left(149\right)-\left(-4\right)=-162$

$\left(130\right)-\left(-90\right)-\left(220\right)=0$

$=-7C-12C\\= - 19C$
