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

13. * SHORT RESPONSE You are measuring Z PQR with a protractor. When
you line up QR with the 20° mark, QP lines up with the 80° mark. Then
you move the protractor so that QR lines up with the 15° mark. What
mark does QP line up with? Explain.
O ALGEBRA Plot the points in a coordinate plane and draw ZABC.
Classify the angle. Then give the coordinates of a point that lies in the
interior of the angle.
