Question

add.
$-27 + (-38) = square$
$-30 + 56 = square$

Explanation:

Step1: Calculate \(-27 + (-38)\)

When adding two negative numbers, we add their absolute values and keep the negative sign. So, \(|-27| = 27\), \(|-38| = 38\), and \(27 + 38 = 65\). Thus, \(-27 + (-38) = -65\).

Step2: Calculate \(-30 + 56\)

When adding a negative and a positive number, we subtract the smaller absolute value from the larger one and take the sign of the number with the larger absolute value. \(| - 30| = 30\), \(|56| = 56\), and \(56 - 30 = 26\). Since \(56\) is positive, \(-30 + 56 = 26\).

Answer:

\(-27 + (-38) = \boxed{-65}\)
\(-30 + 56 = \boxed{26}\)
