Locate irrational numbers on a number line.

When looking to combine radicals I am often reminded to keep things simple. In this video we will explore how to simplify combine two radical expressions if it is with the square root, cube root or any other

In this video playlist I show you how to solve different math problems for Algebra, Geometry, Algebra 2 and Pre-Calculus. The video will provide you with math help using step by step instruction. Math help tutorials is just what...

Approximate square roots.

👉 Learn how to find the 3rd root of an expression. To find the 3rd root of an expression, if the exponent of the expression is a multiple of 3, then the 3rd root of the expression is the base of the expression with an exponent that is...

👉 Learn how to evaluate basic logarithms. Recall that the logarithm of a number says a to the base of another number say b is a number say n which when raised as a power of b gives a. (i.e. log [base b] (a) = n means that b^n = a). Thus,...

👉 Learn how to add or subtract radicals. A radical is a number or an expression under the root symbol. Radicals can only be added or subtracted if the numbers or expressions under the roots are the same for all terms. To add or subtract...

👉 Learn how to find the square root of a number. To find the square root of a number, we identify whether that number which we want to find its square root is a perfect square. This is done by identifying a number which when raised to...

👉 Learn how to simplify the square root of an expression. The square root of an expression is an expression which will multiply itself twice to give the original expression. To simplify the square root of an expression, we...

👉Learn how to solve a quadratic equation by factoring a perfect square trinomial. A perfect square trinomial quadratic equation is of the form y = x^2 +2cx + c^2, where c is a perfet square. There are couple of ways we can solve a...

The video is a tutorial on the basics of powers and roots in mathematics. It covers positive powers, negative powers, roots, and fractional powers, explaining how to write them in index notation, convert negative powers into fractions,...

In this video we discover what the difference of two squares means and how to factorise these ‘special’ quadratics.



To factorise these quadratics, you need to know the square numbers. Any expression that has x-squared as the...

SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow...

Learn about the Pythagorean theorem. The Pythagoras theorem is a fundamental relation among the three sides of a right triangle. It is used to determine the missing length of a right triangle. The Pythagoras theorem states that the...

This video provides an explanation of sequences and how to identify their patterns in order to generate a rule or find the nth term. It covers arithmetic progression, quadratic sequences, and special sequences such as triangular, square,...

👉 Learn how to add or subtract radicals. A radical is a number or an expression under the root symbol. Radicals can only be added or subtracted if the numbers or expressions under the roots are the same for all terms. To add or subtract...

👉 Learn how to find the square root of a number. To find the square root of a number, we identify whether that number which we want to find its square root is a perfect square. This is done by identifying a number which when raised to...

Jeremy skateboards, does parkour, and even magically elevates in this fun video about the definitions of prime, composite, and square numbers. Then his friend Jenny helps him out in each chorus to make the song catchy in a way that won't...
