Understand the signs' rules

Same signs = +
Different signs = -

Meaning:
$+$ $+$ and $-$ $-$ = $-$ $-$
$-$ $-$ and $-$ $-$ = $+$ $+$
$+$ $+$ and $+$ $+$ = $+$ $+$

So, $3 + (- 5)$ $3 + (-5)$ has $+$ $+$ and $-$ $-$ (different signs = negative)

$3 - 5 = - 2$ $3 - 5 = - 2$

How do you evaluate 3+(−5)3+(-5)?
