Math question generator will be able to generate 4 types of math question.
- Sum
- Subtraction
- Mulitplication
- Division
User will be able to select how many question for each types they want, Then your application should be able to keep asking user the question until they finished all of them. After that, give them a score (0-100) for their answer.
Example:
Number of sum questions? 3
Number of sub questions? 2
Number of mulitplication question? 1
Number of division question? 0
You have selected 6 questions to answer in total.
Question: 1+3 = ?
4
Question: 5+15 = ?
21
Question: 2+3 = ?
5
Question: 8-2 = ?
1
Question: 3-1 = ?

Example: Creature Type: Wolf Distance(m): 500 Wolf travels 500(m) in 0.5 hour(s)
Make an area calculator to calculate different 2D shape area. Different shapes would require different questions for the user to answer in order to calculate the result.
Your calculator should be able to support the following shape:
- Circle
- Rectangle
- Square
Example:
type of 2d shape: circle
Radius of the circle: 3
Circle Area: 7.068583471
Example 2:
type of 2d shape: rectangle
Rectangle Length: 5
Rectangle Width: 4
Rectangle Area: 20
