use PEMDAS this is called the order of operations and is an acronym. here is what is stands for
P=Parenthesis
E=Exponents
M=Multiplication
D=Division
A=Addition
S=Subtraction
You have to do whatever is in the parenthesis first then go onto the exponents... then go to the next operation until all things are simplified. Then you can isolate you variable and find the value of it in the expression.

What is an expression that combines numbers and operations?
It is simply a more complicated expression.

order of operations
What does an expression look like in maths?
It is a lot of numbers and letters, combined together with various mathematical operations and functions. Operations such as addition, subtraction, multiplication division, exponentiation etc; functions such as trigonometric ones, logarithms, factorials, etc. An expression cannot have an equals sign (or a less than or more than sign) because then it becomes an equation (inequality). So 3x2 + 2y/sin(x) - 23-x is an expression.
How do you evaluate an expression with more than two operation symbol without exponent and parenthesis?
In Evaluating Expression first,replace each letter in the expression with the assigned value. second,perform the operations in the expression using the correct order of operations and the last you got the answer
What is an expression that combines numbers and operations?
It is simply a more complicated expression.
What is an expression that may contain numbers operations and one or more symbols?
It is an algebraic expression.
What mathematical expression consists of constants variables and operations?
It is a more complicated mathematical expression.
How do you make algebraic expression?
An example of an algebraic expression is: 4x=24. it is basicaly an expression with 1 or more operations, a variable, and an equal sign.
What has numbers and operations signs but no equals signs?
An expression, or, more pedantically, inequalities.

What is an expression that contains numbers operations and one or more variables?
That sounds like the definition for Recursive Formula.
Use algebraic expression in a sentence?
An algebraic expression is a term used in algebra, describing an expression containing one or more numbers, variables, and arithmetic operations. An example sentence would be: They all agreed to algebraic expression seemed impossible.
How is an algebraic expression different from a numeric expression?
An algebraic expression includes one or more variables (x, y, a, b) that can have more than one value, especially with regard to each other when there are two or more.
Explain how to write and evaluate an algebraic expression.one more than the product of a number and seven, decreased by five; evaluate when n = 6?
Sample Response: Replace key words with variables, numbers, and operations. More than is addition, product is multiplication, and decreased by is subtraction. The constants are 1, 7, and 5. The expression is 1 + 7n – 5. To evaluate the expression, substitute 6 in for the variable, and then use order of operations to simplify. The value when n = 6 is 38.
