wot happens when you multiply with a negative number?eg 4x-7=?
We have a convention that:

1) the product of a negative and a negative is positive

These conventions allow arithmetic to be extended consistently to
cover multiplication and division of negative numbers.

In this case:

$
4 \times -7 = - 28
