The correct answer is: C. expression
An expression is a sign or symbol that specifies, operator, and values that produce a result.
An operator is a symbol that tells the computer what to do with the values in an expression. For example, the addition operator (+) tells the computer to add the two values together.
A value is a number, letter, or symbol that represents a quantity or quality. For example, the number 5 is a value, as is the letter A.
A result is the output of an expression. For example, the result of the expression 5 + 2 is 7.
Here are some examples of expressions:
- 5 + 2
- 3 * 4
- 7 – 1
- A + B
- (5 + 2) * 3
As you can see, expressions can be simple or complex. They can also be made up of multiple operators and values.
Expressions are used in many different areas of mathematics, science, and engineering. They are also used in many computer programming languages.
