Pronunciation: /kənˈstreɪnt/ Explain

A constraint is limitation or restriction placed upon a math problem. For example, if a problem states y = 3x - 2, x > 0, the constraint is the limitation x > 0, meaning that x is only allowed to take on positive numbers. One can say, "x is constrained to positive numbers."
