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.

![The image shows a mathematical integral expression. The integral is set up as follows:
\[
\int_{0}^{1} (1 - 2x)^3 \, dx
\]
This expression represents the definite integral of the function \((1 - 2x)^3\) with respect to \(x\), evaluated from the lower limit of 0 to the upper limit of 1. Such integrals are often used in calculus to find the area under a curve between two points, or to solve problems involving accumulation and rates of change.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8d6a2302-be00-405d-bbf6-4b5c194aa6b1%2F04c3d91f-8b44-4a5b-9c56-151962bfbfb8%2Fwkpa90g_processed.png&w=3840&q=75)
