How To: Cram & study effectively for a test

Chau-Minh, a private tutor, discusses cramming and how to do it effectively. This video does not intend to endorse cramming, but if you are probably screwed then you might as well see it. When you cram, don't expect to get a high grade because you lack time. To pull out a high grade, we need to do deletion. Deletion is just like chopping a branch to make the tree smaller. The tree would signify the lectures of your professor. Crossing out the topics that are discussed rarely by the professor ...

How To: Use Excel spreadsheet setup & cell references

In this Excel basic video the instructor shows how to setup a spreadsheet and use cell references. Cell references are used in Excel to refer to other cells in a formula.

How To: Solve an equation by the distributive property

In this simple tutorial the tutor shows how to solve equation by the distributive property. He states that when there is a number which is multiplied to a full equation, we have to multiply each and every term of that equation by that multiplying number. This is called the distributive property as the value is distributed to each and every term inside the equation. He goes on and solves a problem based on this property to give a clear idea of the property. This video shows how to solve equati...

How To: Multiply two fractions together

This video demonstrates the simplest method for multiplying fractions. According to the tutor, one should first identify the highest common factor with which to reduce the two fractions, by themselves, and in relation to each other. The numerators of the two fractions are multiplied and the product is written down as the numerator of the resultant. The same operation is carried out on the denominators of the two fractions, resulting in the denominator of the resultant fraction. The final answ...

How To: Apply the 5th Law of Exponents

In this video the tutor explains the 5th Law of Exponents. He reminds the viewer that when polynomials are multiplied, their exponents get added. Now he states that when a polynomial is raised to another power, the exponents are multiplied instead of adding. The 5th Law of Exponents states that when a polynomial with a power 'a' is raised to a power 'b', then the final power of the exponents is the value of the product of the exponents, i.e., a * b. This video states the 5th Law of Exponents ...

How To: Use the midpoint formula to find midpoint of a line
