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.

![### Objective #7: Graph Functions Involving a Sequence of Transformations
A function involving more than one transformation can be graphed by performing transformations in the following order:
#### Transformations and Their Effects
1. **Horizontal Translations**
- **Function:** \( y = f(x - h) \)
- **Effect:** Shifts \( f \) to the right by \( h \) units.
- **Function:** \( y = f(x + h) \)
- **Effect:** Shifts \( f \) to the left by \( h \) units.
2. **Horizontal Stretching or Shrinking**
- **Function:** \( y = f(bx); b > 1 \)
- **Effect:** Horizontally shrinks \( f \) by dividing each of its \( x \)-coordinates by \( b \).
- **Function:** \( y = f(bx); 0 < b < 1 \)
- **Effect:** Horizontally stretches \( f \) by dividing each of its \( x \)-coordinates by \( b \).
3. **Vertical Stretching or Shrinking**
- **Function:** \( y = af(x); a > 1 \)
- **Effect:** Vertically stretches \( f \) by multiplying each of its \( y \)-coordinates by \( a \).
- **Function:** \( y = af(x); 0 < a < 1 \)
- **Effect:** Vertically shrinks \( f \) by multiplying each of its \( y \)-coordinates by \( a \).
4. **Reflections**
- **Function:** \( y = -f(x) \)
- **Effect:** Reflects \( f \) about the x-axis by changing the signs of \( y \).
- **Function:** \( y = f(-x) \)
- **Effect:** Reflects \( f \) about the y-axis by changing the signs of \( x \).
5. **Vertical Translations**
- **Function:** \( y = f(x) + k \)
- **Effect:** Shifts \( f \) upward by \( k \) units.
- **Function:** \( y = f(x) - k \)
- **Effect:** Shifts \( f \) downward by \( k \) units.
