Thread: How to create math problems by grade level. Please Help Me.

Hi everyone I am new to computer programming, and I need help with creating a code that will create random addition or subtraction from 0-500 depending on their grade level. I know how to create a random for the math and subtraction. I just dont know how to get it to change depending on their grade level. Example I need it to ask their name, grade level, addition or subtraction then five addition or subtraction questions depending on what they chose.

Please help me out.

If you need more detailed information just let me know, and I can break the whole thing down and show you what I have so far.

Thanks for replying so quickly, What I need it to do is ask the user what grade they are in from 1-5 then ask the user if they want to do the addition or subtraction problems, so if the student says they are in the 1st grade it will generate either addition or subtraction problems from 1-100, and if in 2nd grade it will be from 1-200 and so on.

If this is still confusing I can send you an email with an attachment as to what it should look like when it runs.

I think I posted the reply did you get it?

not sure if you ever recieved my reply, but I just need help with how to write the code for the random math generator to recognize their grade level.

ok so first:
// ask the user for their name
// ask the user for their grade level
// ask the user if they want to do the addition or subtraction problems
// generate random addition or subtraction based on their reply while keeping a count on the number of correct answers
// then give them a report of the number of correct answers and the percentage correct.
// finally ask the user if they would like to run the program again.

ok so based on their grade level I need to generate 5 math problems for them to answer. so if they say they are in the third grade and they want to do the addition problems my progam should then begin and ask them a math question from 0-300 five times total. if they answer a problem correctly it will let them know that they are correct and move on to the next math problem. If incorrect it will let them now it was wrong and move on to the next problem. Once they answer all five problems it will then generate a report for them on how they did.

that is what it should look like when the program runs.

the steps are
1. ask an addition or subtraction problem
2. if the answer is correct let them know
3. ask them another math problem ( five times total)
4. once they have answered all 5 problems display how many they got right and how many wrong.

1.the program will ask them if they would like to take the addition or subtraction test. // 1 for addition 2 for subtraction
2. If they choose 1 then all five math problems will be addition.

I have completed these steps:
1. ask the user for their name
2. get their grade level

Now I need to figure out how to compile a code for their math problems and how to add the correct and incorrect total.

For this program, you need to understand properly what it asks. First it says to take name as input, which has practically no relation with the logic. That done, take the grade as input. Remember to keep it in a do while loop and check if input is within 1 to 5. Now initialize a variable with value grade*100
which will be used as limit to generate random integers according to grade (i.e. 100 for 1, 300 for 3, etc.). Take input of addition or subtraction and then generate 2 random integers in a for loop which runs from 1 to 5 (for 5 questions). Every time, it generates 2 random integers within the given limit and then add or subtract them. Take input of the answer and match it with the addition or subtraction result. Keep track of no. of correct answers and no. of wrong answers and after the loop, calculate the result, which you should be able to do by yourself. Keep the whole thing in a do while loop and take input if user wants to continue. if yes, whole thing runs again otherwise - Thank you.

Overall, it is a good program. Practice more programs like these.

Thank you.

So is pseudocode going to help me figure out what to input? I know how my layout should be I just don't know what to type for this to work.

So how would you do this in eclipse or something? I know how to write code for asking the name and grade, but I just don't know how to write a code for the random math problems etc.

I have a java programming book, but it does not teach you how to write a code that can generate random math problems and keep count of correct and incorrect. I have been looking everywhere online for help, why is it so hard?
