Question

How do you simplify `-3*12 - *18 + *72 + 8*75`?

Answer 1

Treating the `*` symbol as multiplication, the given expression makes no sense

Explanation:

If `-3*12color(red)(-* )18...` is meant to be interpreted as
`color(white)("XXX")-3xx12color(red)(-xx)18...`
then either the `color(red)(-)` or the `color(red)(* )` should be omitted
or some additional value needs to be inserted between these operations.
