Question

Simplify: $18+\left(-68\right)$.

Answer 1

Step:Simplification.

Adding a Positive and a Negative Integer:

When we add one positive integer and one negative integer, we subtract the number with the least absolute value from the number with a large absolute value number and put the sign of the number with a larger absolute value to their difference.

$$\begin{gathered} \therefore 18+\left(-68\right)=18-68 \\ =-50 \end{gathered}$$

Therefore, the required answer is $-50$.
