Expression is a combination of ___________, ____________ and _______________Select one or more:a.functionsb.variablesc.constantsd.operatorse.keywords

To fill in the blanks for the statement "Expression is a combination of ___________, ____________ and _______________", we need to consider the components that make up an expression in programming or mathematics.

Parts of an Expression

1. Functions: These perform specific operations on variables or constants. They can take inputs and return outputs.
2. Variables: These are placeholders for values that can change. In expressions, they represent unknown quantities.
3. Constants: These are fixed values that do not change throughout the expression or computation.

Additional Components

• Operators: These are symbols that specify the operation to be performed, such as addition (+), subtraction (-), multiplication (*), and division (/).
• Keywords: While keywords are significant in programming, they generally do not form part of mathematical expressions.

Conclusion

Therefore, the correct choices are functions, variables, and constants.

So, the expression is a combination of functions, variables, and constants.
