## Why am I so Bad at Math? How Can I Improve?

Math is one of those subjects that people believe you either “get it” or you don’t. You have to be a “numbers” person to understand math. But this growing idea isn’t supported by enough evidence to say so. Mathematics just seems to be a subject that requires a lot of practice and time to master and understand, rather than just a subject for “math people”. Nothing always comes easy, no matter the subject. The most successful people utilized what opportunities they had to be successful. Continue reading

## How to Solve my Math Problems – Online Calculators and Services

When students get asked about what subject they hate the most, the majority of them would answer Math. There’s just something about computing numbers, finding unknowns, and graphing equations that students find nearly impossible to understand. No matter how much they listen to the teacher, study guide books that explain step-by-step solutions, review math concepts and practice outside the classroom, it seems as if some math equations, inequalities just cannot be solved. Continue reading

## Common Errors in Calculus Exercises

Practical exercises make an important part of a math course, which helps to deeper understand all theoretical information and further study more complex math sections. Quite often students do not even realize that they make mistakes and why that happens. In this article, we will analyze the most common student’s problems met while solving calculus homework. Continue reading

## How to Get 100 With Nine Different Figures

There are a lot of different math tricks that can impress you with their beauty and compactness. In this post, you will find not only their examples but also will try to create your own. To begin with, a few “Mathematical Curiosities” are introduced by the famous Russian mathematician and physicist Yakov Perelman (1882-1942) in his popular book “Arithmetic for entertainment”. Here are some of them: Continue reading

## The Secret of Perfect Numbers

Numbers accompany us from birth until the last days and we can’t imagine the life without them. Among all the numbers, there are some special ones, named perfect. And despite a lot of papers are devoted to these perfect numbers, only 24 such numbers have been determined so far. So what is special about these numbers? Well, the number is called perfect if it is equal to the sum of all its proper divisors excluding itself. Now, let’s find out more! Continue reading

## Finding Square Root Without a Calculator

All of us widely use calculators to perform mathematical operations. Obviously, these machines were invented by people, who determined their work according to the certain algorithms for quick count. In this article, we’re going to tell you about one of such algorithms. We’ll also show how you can extract square roots in column and you’ll see that the result of this operation can be received with arbitrary precision; we can find any digits number in its decimal representation, even if it turns irrational.
