    That's what we're gonna do.

    Now, let's look. We've got some braces, followed by some brackets with some parentheses inside of them. So, we always start with the innermost parenthesis, then work our way out.

    \{3(-6)+(-3)-4[2(-4)-7]\}

    So, we begin by focusin on

    [2(-4)-7]

    What do we need to do here?
