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.

Caren rode her bicycle on a straight road from home to school. She recorded her velocity v(t), in
miles per hour, for selected values of t over the interval [0, 2.4] hours, as showed in the table
above. For 0<t < 2.4 , v(t) > 0.
(a) Use the date in the table to approximate v'(1.5). Show computations that lead to your answer.
Indicate unit of measure.
(b) Using correct units, interpret the meaning of S* v(t)dt in the context of the problem.
Approximate S*v(t)dt using a trapezoid sum with three subintervals of equal length and
values from the table.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe65123c4-fdee-4d8e-b5a5-7168c1e6f9b1%2F1719f94d-63d7-4e71-9f93-81b915052a98%2F7eu68be_processed.png&w=3840&q=75)
