Question

1. -51 + (-42) = ______

Explanation:

Step1: Recall the rule for adding two negative numbers

When adding two negative numbers, we add their absolute values and keep the negative sign. So, for \(-51 + (-42)\), we first find the absolute values of \(-51\) and \(-42\), which are \(51\) and \(42\) respectively.

Step2: Add the absolute values

Add the absolute values: \(51 + 42 = 93\).

Step3: Apply the negative sign

Since both numbers are negative, the result will be negative. So, \(-51 + (-42)=-(51 + 42)=-93\).

Answer:

\(-93\)
