Answering mathematics questions is actually a good way to make money. You could earn money and help people to study maths in one go.
Some of us who ever studied maths in high school know that not every of our friends are good at mathematics. They need someone to help them by telling them the steps to do a particular problem. Since we live in information age, some of them started to look for help by putting their problems in Question and Answer forums. Believe it or not, there is a way to make money by helping them answer their questions.
Of course there is no way that the person having the problem is going to pay you for your assistance. But there are programmers who make a living by selling step-by-step mathematic solver for these students. You just have to google up “website selling step-by-step mathematic solvers” to find them. Among the search result, you will have to find a website that have affiliate service. Having affiliate service means that the website is going to pay anyone who refer a sales to said website a portion of the sales, provided the referer already have an affiliate account.
After you find a website selling mathematic solvers that have affiliate service, you will have to sign up to get an affiliate account along with your affiliate links. You have to note that in any affiliate website, the affiliate code is going to vary depending on the products you want to sell. You have to learn more about their products and what problems their products are capable to solve.
Choose products that you want to sell and save your affiliate links to said products in notepad. Now, you will have to find some question and answer forum where you can start answering questions and get paid for it. I would suggest you to google up “question and answer” to find those sites. Google is really your friend when you need to find things in the net.
Anyway, I am going to list three question and answer forum for you.
This is the biggest question and answer forum I know. This site is visited by millions of students from all part of the world. If you already have a Yahoo!account you just need to log in. Otherwise you will need to sign up before you can answer any question.
