ABSTRACT: As graphics calculators are mainly devices for student learning, it is important that curricula and examinations are constructed to incorporate them in a coherent way. Three recent developments in graphics calculators are described and analysed to determine their .

The purpose of this project is to implement a traditional simple digital calculator that performs the four basic operations; Addition, Subtraction, Multiplication, and Division of 8 bits unsigned numbers. Nexys4 board was used to manage four computations, input functions and output functions. 16 switches on the board will be the input, and output will be displayed on the seven-segment on the board. LEDs on the board will be used to show the sign of results, remainder, and process done or not. The Digital Simple Calculator consists of three main portions in order to achieve the goal. First portion is the input block which will accept inputs from the switches on the board, then transfer to four registers to determine what two 8 bits expressible numeric inputs are and storage of the inputs. The second portion is the Finite State Machine which will determine the state of the inputs and the logic will be responsible for the actual calculation of the result. The third portion will be the .

Evidence from research has proven calculators to be quite effective tools for problem solving, reinforcement of computational skills, pattern recognition, and number sense. Yet, many teachers continue to believe that they can bring more harm than good in the learning of mathematics, therefore their use for instruction should never be encouraged. This paper presents various possibilities on how the calculators
