Identify characteristics of the contexts that inform you of which meaning it takes on. Describe these characteristics in a way that would make sense to a 6th grade student. Meaning one: (cid:884) (cid:885), (cid:1876) (cid:883). (cid:886), (cid:1876) (cid:1877) (take away)- the - means that two values are being subtracted from one another, comparing the two values to each other.
