    You are correct. With parentheses, you really do not need to use the 'X' to represent multiplication.

    and 24/ (-8) is 24/ -8

    I'm not sure what you mean by "a x -3". Certainly that say "2 times -3" which is -6.

    and 24/ (-8) is 24/ -8
    Yes. and, of course, 24/(-8)= -3. Some people would object to "24/-8" on the grounds that it looks like you have two operations (division: /) and (subtraction: -) without a number between them.
