# What do they mean write a mathematical expression

What is a math expression? An expression is the sum or difference of two or more terms. It is a mathematical statement e. MORE In math mean is what? An any expression is also a statement -- an "expression statement". See also the link to the related question I gave above. I figured leaving that information out would avoid extra complexity, especially since expressions as statements aren't very widely used.

And since every function call on a line of its own is an expression statement, they are very widely used. I don't see why being correct adds complexity here.

Expressions are combinations of values and operators and always evaluate down to a single value. A statement is every other instruction. Some statements contain expressions.

## What does expression mean in math

An expression is an instruction that combines values and operators and always evaluates down to a single value. For example, this is an expression: This expression evaluates down to the single integer value 4.

Technically, this is also an expression: When I say values and operators, this isn't limited to math problems: The function call int '5' evaluates to the function's return value, 5. No matter how big an expression is, it evaluates down to a single value: A Python statement is pretty much everything else that isn't an expression.

Here's an assignment statement:Jun 18,  · Learning how to simplify algebraic expressions is a key part of mastering basic algebra and an extremely valuable tool for all mathematicians to have under their belt.

Simplification allows a mathematician to change a complex, long, and/or awkward expression into a simpler or more convenient one that's equivalent%(25). This chapter describes JavaScript's expressions and operators, including assignment, comparison, arithmetic, bitwise, logical, string, ternary and more.

A complete and detailed list of operators and expressions is also available in the reference. caninariojana.comtEE.B.6 Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.

## Simplifying Algebraic Expressions

It means to isolate y on one side of the equation and on the other side of the equation have an expression of x’s equal to y that does not contain a y. Views · View 1 Upvoter Carl Christian Barfield, I study functions all day, for various innovative purposes.

An algebraic expression is one or more algebraic terms in a phrase. It can include variables, In this expression, the variables are x and y. We call these letters "variables" because the numbers they represent can vary—that is, . Meaning of expression. What does expression mean?
