How do you describe variables in an experiment operationally?
Variables work by telling you what you need to change, what to observe, and what to keep the same in a experiment.
Why do you need to keep variables the same?
In programming, variables change all the time. In scientific testing you control variables to determine what other changes occur.
How do you use variable in an addition or subtraction?
well, if you want to add apples to bananas you can't do that it's the same with variables, the coefficients can be different but to add and subtract the variables have to be the same for ex: you can't do 4x+3y because they have different variables you can do 4x+3x because they have the same variables all you do is add the coefficients and keep the variable so you would get 7x
The variables in an experiment that stay the same?
These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.
Are constant variables and independent variables the same?
No they are not the same. A constant variable keeps going at a constant rate.
What is the scientific word for what you keep the same?
The control variables.

If you were doing an experiment to determine the effects of x ray on seed germination what variables woild you need to keep the same for all test groups?

What is a cotrolled experiment?
It means that except for the independent variable (the only factor that you change) you remain the other variables constant. To keep the control variables the same. Then this is a controlled experiment (fair test). Hope this helps :)
Is scientists keep all variables constant true or false?
independent variable
What are the terms that contain the same variables with corresponding variables having the same exponent?
like terms
What does Variables mean for a science project?
A variable means that something that you can change, measure, or keep the same. Example: Responding variable: The variable you can measure. Controlled variable: The variable you keep the same. Manipulated variable: The variable that you change.

Do you have to use the same variables for all equations when creating a system of equations?
The idea is to work with the same variables, but it is possible that some of the variables are missing in some of the equations.
