Question

Minus into plus is equal to _____.

Answer 1

Since, the multiplication of a positive and a negative integer results in a negative integer.

In general, for any two positive integers $a$ and $b$ we can say

$a\times \left(-b\right)=\left(-a\right)\times b=-\left(a\times b\right)$

Hence, minus into plus is equal to minus i.e.,

$\left(-\right)\times \left(+\right)=\left(-\right)$.

For example:

$$\begin{gathered} \left(-2\right)\times \left(3\right)=-\left(2\times 3\right)=-6 \\ \left(-5\right)\times \left(4\right)=-\left(5\times 4\right)=-20 \end{gathered}$$

Hence, minus into plus is equal to minus.
