Subtract and completely simplify: 72-32{“version”:”1.1″,”math”:”72-32″} Enter the exact simplified answer in the box below. You may communicate your response in any of several ways.  You may use the templates found by selecting the “+” sign, then Equation, then Graphical Equation to enter your answer in mathematical notation.  If you use the Equation tool, make sure your response looks exactly like you want it to look. You may instead enter a verbal description of your answer.  As an example, to describe the answer -2×3{“version”:”1.1″,”math”:”-2×3″}, you could type “the negative square root of 2x cubed, where 2 and x cubed are under the square root.”  A third option is to type customary symbolic notation, like “-sqrt(2x^3).”  Bottom line: clearly communicate your response so that it can be understood and manually scored.
