Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

Q3
![### Chapter 8 Question 3.
Selling used cars is often a pain,
A lot of selling to do for very little gain
My used car lot has about 36 cars,
Sometimes, washing them down gives me serious scars.
The average car on my lot sells for a 7245 dollar
With a standard deviation of 2500, it makes me holler!
The 95% confidence interval is required to estimate the population mean
Whether we fall in the normal range or not, remains to be seen!
What distribution makes most sense to use and why,
My manager wants me to explain everything to him, oh my!
