Challenge #1: 2 or 3 operands per equation?
Now that you understand how this code works, complete it in order for the Maths teacher to be able to chose the number of operands per equations. For instance, if the Maths teacher chooses two operands it will generate equations such as “2+7”. If the teacher chooses three operands, an example of equation could be “2+4-7”.
Challenge #2: Find the missing operand
Change the code to generate equations with a missing operand. For instance: “2 + ??? = 9”
Challenge #3: Linear Equations
Change the code to generate linear equations. For instance: “3x + 2 = 11”
Challenge #4: Quadratic Equations
Change the code to generate quadratic equations. For instance: “4x2 + 5x + 2 = 0″
