Writing Expressions
Writing expressions refers to the process of representing mathematical operations using symbols and variables. In this context, fundamental operations typically include addition, subtraction, multiplication, and division. By writing expressions in terms of these fundamental operations, mathematicians and scientists can better understand and analyze complex equations and systems.
Percentages
A percentage is a number or ratio expressed as a fraction of 100.
Reading Graphs
Graphs are visual aids that provide summaries or can illustrate a complex process.
