Question

Find the sum of $\left(-312\right)$, $39$ and $192$.

Answer 1

Calculate the sum of the given numbers:

Given numbers: $\left(-312\right)$, $39$ and $192$.

Thus, $\left(-312\right)+39+192=\left(-312+192\right)+39$

$$\begin{gathered} \left(-312\right)+39+192=\left(-120\right)+39 \\ =\left(39-120\right) \\ =-81 \end{gathered}$$

Therefore, the sum of the given numbers is $\mathrm{-}\mathrm{81}$.
