Question

1. $(-7)+(-10)=$

Explanation:

Step1: Recall rule for adding negative numbers

When adding two negative numbers, we add their absolute values and keep the negative sign. So, for \((-7)+(-10)\), we first find the absolute values of \(-7\) and \(-10\), which are \(7\) and \(10\) respectively.

Step2: Add the absolute values

Add the absolute values: \(7 + 10 = 17\).

Step3: Apply the negative sign

Since both numbers are negative, the result should be negative. So, \((-7)+(-10)=-(7 + 10)=-17\).

Answer:

\(-17\)
