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: 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

How To: Add and subtract to solve equations

In this video the tutor shows how to add/subtract to solve equations. He says that when we are trying to solve simple equations we need to perform the same operation on both the sides of the equation i.e. if we are adding something on one side of the equation we need to add the same thing on the other side of the equation too. Similarly for the subtraction too. He says that by doing this we still maintain the equality of the equation. He shows how to do this with an example. This video gives ...

How To: Draw a dotted/solid line when graphing an inequality

In this video the tutor shows when to use a dotted line and when to use a solid line while graphing lines in coordinate geometry.
