How To: Solve the Rubik's Cube inspired Square One puzzle

So, you can solve the Rubik's Cube, good for you, but what about the Square One? Erno Rubik is nothing compared to Karel Hršel and Vojtech Kopský, who invented the Square One puzzle, also called by its full title, "Back to Square One", or its shorter name of "Cube 21". It's shaped like a Rubik's Cube, but it's cut like a freak show, adding that layer of difficulty that challenges you.

How To: Determine math proportions with the Square-Cube Law

Ever watch a cheesy movie and say "That monster is so FAKE!" but not really understand why? Well monstrous monsters are governed by a little biological rule called the Square-Cube Law, a scientific term combining math, anatomy and physics into one educational tool to recognize theatrical baloney when you see it. Just watch this video to see the explanation of the Cube-Square Rule, how it works and its ramifications for our favorite B-Movie pet monsters.

How To: Simplify square roots w/ product & quotient rules

In this math tutorial, you will learn how to simplify square roots with product and quotient rules. To begin, you will need to multiply the square roots so that the two square roots in your equation are reduced down into one. The rule for non-negative "A" and "B" is that the square root of "A" multiplied by the square root of "B" yields the square root of A x B.

How To: Solve the acid cube Square One puzzle

Watch this video tutorial to see how to solve the acid cube Square One puzzle. There's a few things you should know before even trying to solve the Square-1 puzzle, which is knowing how to solve the Rubik's Cube. Then you need to know the notation for rotating the Square One, also known as Back to Square One and Cube 21. Next you need to know a few algorithms and you're halfway to solving the challenging puzzle.

How To: Simplify square roots in less than a minute

A square root of a number is a value which when multiplied to it self gives you the original number. The square roots of perfect squares are whole numbers. Like square root of 9 is 3, because 3 times 3 is 9. Similarly square root of 81 is 9 because 9 times 9 is 81. Others numbers do not have a perfect square root and in those cases you can only simplify the number to an extent. So to find out the square root of any number first you need to factorize that number. Factorize the number into smal...

How To: Simplify radicals before adding or subtracting

This video in the Education category will show you how to simplify radicals before adding or subtracting. By doing this you will find all like radicals which will then ensure that you have all radicals in the simplest form. Let’s say you want to subtract square root of 45 from 3 square roots of 20. Now square root of 45 can be written as square root of 9 x square root of 5. Because, 9 and 5 are factors of 45. Similarly, 3 square roots of 20 can be simplified to 3 x square root of 4 x square r...

How To: Simplify rational expressions

When you need to compute the square root of a number you can do it by breaking it into perfect squares. When you can split the given number into small perfect squares you can cancel out the square root of the expression to the square of the perfect squares. You cannot always write the number inside the square root as a perfect square, but try to write this number as a product of a perfect square and another number. Now you can pull out the perfect square out of the radical and leave the remai...

How To: Solve & find the least common multiple

This is a mathematical instructional video on how to find the least common multiple. Let us now find the least common multiple for 25, 100, 18. This can be written as 5 square, 2 square multiplied by 5 square, 2 multiplied by 3 square. The highest factor in these numbers are, 5 square, 2 square and square. If you multiply 5 square with 2 square and 3 square you will get the final answer as 900. This is the least common multiple of 25, 100, and 18. This method is explained very clearly in this...
