Create a mathematics game for children. The program should allow the user to choose different mode of the game:

-PracticeMode (Answer will be given after the user answer the question)

-ScoringMode (10 questions in a game, answer will not be given after the user answer the questions, it will show the scoring of the user at the end of the game.)

-AnswerMode (User give the question and answer, the program will display the answer to user)

DifficultyLevels:

-Easy (add(+) and subtraction(–) only)

-Medium (add(+), subtraction(-), and multiplication(X) only)

-Hard (add(+), subtraction(-), multiplication(X), and division(/))

Guideline:

-All questions should consist of TWO numbers and an operator (+, -, X, /), which are RANDOM.

-Addition and Subtraction questions, both of the numbers in the questions should not more than 100.

-Multiplication, both of the numbers of the question should not more than 12.

-Division, the first number should not more than 100, and the second number of the question should not more than 10.

Hypotenuse Calculations) Define a method hypotenuse that calculates the hypotenuse of a right triangle when the lengths of the other two sides are given. The method should take two arguments of type double and return the hypotenuse as a double. Incorporate this method into an application that reads values for sidel and side 2 and performs the calculation with the hypotenuse method. Use Math methods pow and sqrt to determine the length of the hypotenuse for each of the triangles in Fig. $6.15 .[$ Note: Class Math also provides method hypot to perform this calculation.]
