Question

find each sum.

1. $-7 + (-1) = \underline{quadquad}$

Explanation:

Step1: Recall rule for adding negatives

When adding two negative numbers, we add their absolute values and keep the negative sign. So, for \(-7 + (-1)\), we first find the absolute values of \(-7\) and \(-1\), which are \(7\) and \(1\) respectively.

Step2: Add the absolute values

Add the absolute values: \(7 + 1 = 8\).

Step3: Apply the negative sign

Since both numbers are negative, the sum is negative. So, \(-7 + (-1) = - (7 + 1) = -8\).

Answer:

\(-8\)
