Further explanation

Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.

The main composition of algebraic expressions are:

1. phrases

algebraic forms separated by arithmetic operations

consisting of one phrase (monomial) to many phrases (polynomial)

2. variable

is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.

3. constants

is a fixed value, can be a number

4. arithmetic operations

operations $\boxed{+},\boxed{-},\boxed{:},\boxed{x}$

Words that can be used to express arithmetic operations are:

An algebraic expression for the sum of 15 and x, plus 7

1. the sum of 15 and x

$\boxed{the\:sum}$ means to use arithmetic $\boxed{+}$ operations

$\boxed{and}$ means the sum of both 15 and x

$\boxed{,}$ means 15 + x is added up first, so we use parentheses

2. plus 7

$\boxed{plus}$ means using arithmetic operations $\boxed{+}$
