Prime numbers aren't too hard to define, but they still puzzle professional mathematicians. Believe it or not, all over the word computers are chugging away, trying to find the next biggest prime! Bigger and bigger prime numbers help keep your credit card info safe through really cool encryption techniques. So prime numbers really matter every day, and you can learn how they are defined in this tutorial.
In math, it's often important to change a fraction from one type to another. It can help you work with the fraction in an equation or help make more sense of an answer. This tutorial shows you how to convert an improper fraction to a mixed fraction.
This tutorial uses something called a factor tree to find the greatest common factor of two numbers. Creating a factor tree for a number makes it easier to find its prime factors. These prime factors are used to help find the greatest common factor. Watch this tutorial and learn how to find the greatest common factor using a factor tree.
To find the greatest common factor (GCF) between numbers, take each number and write its prime factorization. Then, identify the factors common to each number and multiply those common factors together. Bam! The GCF! To see an example worked out, check out this tutorial!
To write the prime factorization for a number, it's often useful to use something called a factor tree. Follow along with this tutorial and see how to use a factor tree to find the prime factorization of a given number.
If the only factors a number are 1 and itself, then that number is prime. A number that is not prime is called composite. Learn about prime and composite numbers by watching this tutorial!
If you want to compare different types of numbers, start by converting all of them to one type of number! This tutorial shows you an example of this involving fractions and decimals!
It's important to know how to make equivalent fractions. In this tutorial, you'll see how to create an equivalent fraction when you have a fraction and the denominator of an equivalent fraction!
When you get a fraction as an answer, you're usually asked to write it in its simplest form. This tutorial shows you how to use the GCF of the numerator and denominator to fully simplify a fraction!
The term 'factor' is seen a lot in math, so it's important to know what it means. This tutorial introduces you to that term!
Being able to take out a greatest common factor can make a problem easier to work with, but before you do that, you need to understand what a greatest common factor is. This tutorial explains exactly that!
Are you ever asked to put your fraction answer into simplest form? Wonder what 'simplest form' means? This tutorial explores exactly that! Take a look at what a fraction needs in order to be in simplest form.
Looking for practice finding the least common multiple (LCM)? Then be sure to check out this tutorial! Follow along with this tutorial as it goes through the process of listing multiples of given numbers and identifying the smallest of these multiples in order to find the LCM. Take a look!
Looking for practice finding the least common multiple (LCM)? Then be sure to check out this tutorial! Follow along with this tutorial as it goes through the process of using a factor tree for each given number in order to help find the LCM.
Ordering fractions from least to greatest? Don't have common denominators? You could find the least common denominator (LCD) of the fractions and write equivalent fractions with this LCD. Then, compare the numerators to figure out their order from least to greatest! This tutorial shows you how!
Learning about divisibility? Take a look at this tutorial! You'll see how to test if a number is divisible by 2, 3, 5, 6, and 10 using some cool tricks!
Trying to find all the factors of a number? Setting up a table can be really helpful! Check out this tutorial to see how to use a table to find all the factors of a given number.
The greatest common factor (GCF) is the largest factor two or more numbers have in common. Finding the GCF can be very useful in simplifying an expression or solving an equation. In this tutorial, see how to identify the GCF of an expression and factor it out. Check it out!
The greatest common factor (GCF) is the largest factor two or more numbers have in common. Finding the GCF can be very useful in simplifying an expression or solving an equation. Watch this tutorial and learn what it takes to find the GCF of two numbers!
Ordering fractions from least to greatest? Don't have common denominators? Find a common denominator by multiplying the denominators together. Use that common denominator to create equivalent fractions. Then, compare the numerators to figure out which is bigger! This tutorial shows you how!
Being able to find multiples of a number is important, especially if you want to find the least common multiple (LCM) between numbers. In this tutorial, you'll be introduced to the term multiple. You'll also see how to find multiples of a given number!
Sometimes terms in math do a pretty good job of describing the thing they name. This is the case with common multiple and least common multiple (LCM). A common multiple is a multiple that two or more numbers have in common. You can probably guess what a least common multiple is! To get more information about these terms, check out this tutorial!
Finding equivalent fractions is an important part of things like adding, subtracting, and comparing fractions. But what are they? In this tutorial, you'll learn that equivalent fractions are just fractions that have the same value, even though they may look very different! Take a look at equivalent fractions by watching this tutorial!
Divisibility is an important part of math. When you're finding the factors of a number, you need to figure out what numbers you number is divisible by. Take a look at this tutorial and learn about divisibility!
Did you know that a fraction just represents a division? To turn a fraction into a decimal, divide the numerator by the denominator. In this tutorial, see how to convert a fraction into the terminating decimal it represents.
If you have a terminating decimal, you can rewrite it as a fraction! Check out this tutorial to learn how to convert a terminating decimal into a fraction.
Did you know that a fraction just represents a division? To turn a fraction into a decimal, divide the numerator by the denominator. In this tutorial, see how to convert a fraction into the repeating decimal it represents.
A terminating decimal is a decimal that ends. It's a decimal with a finite number of digits. Did you know that all terminating decimals can be rewritten as fractions? Watch this tutorial to learn about terminating decimals and see some examples!
A repeating decimal is a decimal that has a digit, or a block of digits, that repeat over and over and over again without ever ending. Did you know that all repeating decimals can be rewritten as fractions? To make these kinds of decimals easier to write, there's a special notation you can use! Learn about repeating decimals in this tutorial.
