This video introduces basic concepts related to statistics, focusing on the idea of variables. Variables are defined as numbers or characteristics that can be counted or measured. The video gives examples such as age, length,...

A video entitled "Solve Real World Situations" that covers solving a system of equations modeled by a real-world situation and interpreting the solution.

What is the butterfly effect? The Real Butterfly Effect -- Imagine this scenario, a butterfly flutters its wings in Brazil, and it sets off a cascade of events over the course of time, which results in the...

Howcast - An algebraic equation is an equation that includes one or more variables. These equations can be solved as long as the number of variables does not exceed the number of equations.

When you normalize a set of data, you map the original data range into another scale. The steps for normalizing a data set are described here.

Pupil outcome: I can evaluate and develop logic statements using Boolean logic. Key learning points: - A logic statement is a statement that evaluates to either True or False. - You can write a logic statement to represent an outcome...

Pupil outcome: I can plan an investigation to identify the effects of water resistance. Key learning points: - Water Resistance is a force which acts to slow down or stop objects that are moving through liquid. - Water resistance acts in...

Pupil outcome: I can set up a comparative test investigation to find out what plants need. Key learning points: - Scientists can investigate what plants need by observing plant growth when requirements are removed. - In a comparative...

Pupil outcome: I can substitute particular values into a generalised algebraic statement to find a sense of how the value of the expression changes. Key learning points: - Expressions and formulae in context can be evaluated for...

In this video, we practice direct, inverse, and joint variation problems.

A literal equation is an equation with more than one variable. These problems will sometimes have you solve for a variable, so that your solution is in terms of other variables. This will happen very often in formulas for science.

Watch this video for basic definitions and applications of that Algebra ideas of domain and range.

This is the second of two videos on solving systems of equations using the substitution method.

In this video you will learn how to solve equations with variables on both sides, such as 3x + 3 = x + 7

This video practices solving systems of equations by substitution and elimination.
