NSN - Adding and Subtracting Fractions. NSN - Basic Number Properties. Purplemath There are three basic properties of numbers, and your textbook will probably have just a little section on these properties, somewhere near the beginning of the course, and then you'll probably never see them again (until the beginning of the next course).

My impression is that covering these properties is a holdover from the "New Math" fiasco of the 1960s. While the topic will start to become relevant in matrix algebra and calculus (and become amazingly important in advanced math, a couple years after calculus), they really don't matter a whole lot now. MathHelp.com Why not? Distributive Property Affiliate The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Why is the following true? Since they distributed through the parentheses, this is true by the Distributive Property. Use the Distributive Property to rearrange: 4x – 8 The Distributive Property either takes something through a parentheses or else factors something out.

A fraction is a number that names part of a whole or part of a group. The denominator represents the total number of equal parts the whole is divided into. A ratio is a comparison of two quantities. For example, in a group of five students in which there are 4 boys and 1 girl, the fraction of the group that is female is . The fraction of the group that is male is . NSN - Fractions Rap.

NSN - Reason for Learning Factoring. NSN - Integers - reason why two negatives make a positive. Here are ‘The Rules’ and ‘The Reasons’, ‘The How’ and ‘The Why’ for Multiplying Integers.

I uploaded a couple pages of my Math Model Book for a ‘Pair-a-Dimes’ post, “Assessment & Rote Learning: Math Conundrums“… and thought I would share these very practical resources here. The first page has The Rules for Multiplying and Dividing Integers. Next, using counters, I look at Why the Rules for Multiplying Integers Work*. *It is very important to have pre-taught the concept of zero before this lesson, (the same negative and positive number together cancel each other out: together -4 and +4 = 0). But what about division you might ask? If 3 x 4 = 12 Then 12 ÷ 4 = 3 and 12 ÷ 3 = 4 So if, -3 x -4 = +12 Then +12 ÷ – 4 = -3 and +12 ÷ -3 = -4 This makes further sense to students when they realize that multiplying two integers with opposite signs = negative, and they can see that the same rings true for division as well.

Difference Between a Percentage and a Rate (as explained by medical field)

Often we hear the question, "What is the difference between a percentage and a rate?

" They are both calculated using a numerator and a denominator. However, the relationship between the numerator and denominator makes the difference. Percentages Indicators which use percentage are the most commonly used indicator type in healthcare. Most of the Joint Commission measures monitor percentages to measure compliance. Guidelines for Percentages: Numerator and denominator are the same unit of measure Both the numerator and denominator are positive whole numbers The numerator is never greater than the denominator Example: An AMI patient is admitted. Percentages are charted on a p chart, where p stands for proportion. StudyJams. Sign in -or- Register.
