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.

Below is an interpretation of the general formulas needed:
##### Distance Formula:
The distance \( d \) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
##### Slope Formula:
The slope \( m \) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
---
These points and formulas can be used to solve geometric problems such as finding the lengths of the sides of polygons, determining the slope of a line, or verifying the characteristics of geometric figures in a coordinate plane.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2ad5e9c7-ca41-4a3c-8bb4-77208fd1df10%2Fd8b0600c-c9c0-4eb3-b580-662b0e96e96a%2F747h7ea_processed.jpeg&w=3840&q=75)
