Key Learning Outcomes for this video:
1. To be able to change the subject of an equation or a formula by rearranging.
Rearranging equations changes the form of the equation to display it in a different way. This is sometimes called changing the subject.
How to rearrange equations step by step:
A. Identify the variable you need to make the subject.
B. Isolate the variable by: removing any fractions by multiplying by the denominator/s, dividing by the coefficient of the variable, and by square rooting or squaring both sides of the equation
C. Perform inverse operations so that each term that needs to be made the subject is on one side of the equation.
