  If your child doesn't have the following concept, please wait until he/she has the concept.
  When he/she who doesn't have basic math concept, they might lose the interest of Coding.

1. Check if he/she has "Variable Concept"
   ex) num1=10, num2=20
   sum=num1+num2 , product=num1*num2
   What is sum? What is product?
   
2. Check if he/she has "Range Concept"
   ex) num=10,11,12,13,14,15
   what is range of the variable "num"?
   
3. Check if he/she has "Comparison Concept"
   ex) num1>num2
   which variable is bigger?
   which variable is smaller?
   
4. Tell what is even numbers from 1 to 10
   Tell what is odd numbers from 1 to 10
   
5. num=12
   What is factors of the variable "num"?
   
6. num1=4, num2=10

8. What is square? What is cube?
   
9. num=5
   Is the variable "num" prime? Why?
   
10. Tell prime numbers from 1to 10
