So we'd solve this like

(-30(-7)-(210(-3))    ( now we have to multiply these)

=(210-(-630)  ( as when there are two minus signs both of them get cut and we just have plus sign so we'd do the same out here)

=210 + 630 (now simply add them)

=840  ANSWER

i hope uve understood by now but if not then pls be free to ask!

i hope this helps!

There is an odd number of brackets.  

Rosala has chosen to ignor the first one.

That is probably what you meant.

good work Rosala.
