**EVALUATING ALGEBRAIC EXPRESSIONS**

- To evaluate an algebraic expression, replace the variables with their values. Then, find the value of the numerical expression using the order of operations.
- Replace a with 7, b with 3, and x with 1.
- Evaluate 7² and 3³, then multiply 4 and 1.
- Subtract.

**How To: Given two points from a linear function, calculate and interpret the slope.**

- Determine the units for output and input values.
- Calculate the change of output values and change of input values.
- Interpret the slope as the change in output values per unit of the input value.

The definition of an interpretation is an explanation of a view of a person, place, work, thing, etc. An example of interpretation is **a feminist perspective on a work of literature**. noun. 1. A performer's distinctive personal version of a song, dance, piece of music, or role; a rendering.

In these contexts an interpretation is a function that **provides the extension of symbols and strings of symbols of an object language**. For example, an interpretation function could take the predicate T (for "tall") and assign it the extension {a} (for "Abraham Lincoln").

If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x). **Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context**.

To me, "justify" means **to lay out the mathematical thought process step by step, so that the line from the starting point to the ending point is connected**. It is a bit less formal than a proof, which has certain logical requirements, but it means, "show enough work so that I know that you get the whole thing."

m = change in y change in x. In other words, **the slope of a line is the change in the y variable over the change in the x variable**. If the change in the x variable is one, then the slope is: m = change in y 1. The slope is interpreted as the change of y for a one unit increase in x.

Are facts open to interpretation? A fact - or say a REAL fact, which is true with out any assumptions, **can not be interpreted**. 1 + 1 = 2 is not a fact, its a statement based on a number of assumptions or standards.

**The slope of a line is the rise over the run**. If the slope is given by an integer or decimal value we can always put it over the number 1. In this case, the line rises by the slope when it runs 1. "Runs 1" means that the x value increases by 1 unit.

First, **mathematics notation is subject to interpretation**. Looking at your example, we have that 1+1=0 in modulo-2 arithmetic. Most mathematics requires context to be understood.

Unlike translation which focuses on written communication, interpretation is all about verbal communication. The three basic interpretation modes are **simultaneous interpretation (SI), consecutive interpretation, and whispered interpretation**.

Some of the main topics coming under algebra include **Basics of algebra, exponents, simplification of algebraic expressions, polynomials, quadratic equations**, etc. In BYJU'S, students will get the complete details of algebra, including its equations, terms, formulas, etc.

In algebraic expressions, letters represent variables. These letters are actually **numbers in disguise**. In this expression, the variables are x and y. We call these letters "variables" because the numbers they represent can vary—that is, we can substitute one or more numbers for the letters in the expression.

You should already be familiar with **algebra and geometry** before learning trigonometry. From algebra, you should be comfortable with manipulating algebraic expressions and solving equations. From geometry, you should know about similar triangles, the Pythagorean theorem, and a few other things, but not a great deal.

The main difference between mathematics and numeracy is that **mathematics is the broad study of numbers, quantities, geometry and forms while numeracy is one's knowledge and skills in mathematics and its use in real life**.

Sixth grade is **the year that students really get started on algebra**. They learn how to read, write, and evaluate algebraic expressions and equations in which a letter (also called a variable) stands in for an unknown number. For example, they'll find the value of X in the equation X – 32 = 14.

An algebraic formula is **an equation, a rule written using mathematical and algebraic symbols**. It is an equation that involves algebraic expressions on both sides. The algebraic formula is a short quick formula to solve complex algebraic calculations.

Students who learn with manipulatives **can become too reliant on the object and context**, and as a result, have difficulty transferring their knowledge to new contexts, different testing formats, or to abstract representations (e.g., algebraic expressions) of the problem (1), (3), (6).

In algebra, an equation can be defined as **a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value**. The most basic and common algebraic equations in math consist of one or more variables.

Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different. In an expression, only like terms can be combined. We combine like terms **to shorten and simplify algebraic expressions, so we can work with them more easily**.
