I have been using this site for 10 minutes, I really cannot give a good assessment. I do believe that a users manual should be more accessible from the home page so you can review the user guide while using the form filler.

This is a very handy tool
This is a very handy tool, the only problem is the price, you could give a discount for students or something, otherwise a very lifesaving thing.

What is an example of an open equation?
Answer and Explanation: Any equation that contains variables, and the truth value of the equation depends on the values of those variables is called an open equation. An example of an open equation is as follows: 3x + 1 = 10.
What does an open equation mean?
Equations can be true, false, or open. That is, if an equation is a true statement, then it is a true equation, if an equation is a false statement, then it is a false equation, and if an equation's truth value depends on the values of the variables in the equation, then we call it an open equation.
What does it mean if an equation is true false or open?
true is when a problem is true and equals what is said it equals. False is when it doesn't equal what is says it equal. Open sentence is when there is a variable in the problem or equation.
How do you determine if an equation is true?
To make a true equation, check your math to make sure that the values on each side of the equals sign are the same. Ensure that the numerical values on both sides of the “=” sign are the same to make a true equation. For example, 9 = 9 is a true equation. 5 + 4 = 9 is a true equation.
What is an example of an open sentence?
Open Sentence. In mathematics: When we don't know if a statement is true or false. Until we know what the value of “x” is, we don't know if “x + 2 = 3” is true or false.
What is an open expression in math?
A mathematical sentence makes a statement about two expressions. An open sentence in math means that it uses variables, meaning that it is not known whether the mathematical sentence is true or false. A closed sentence, on the other hand, is a mathematical sentence that is known to be either true or false.
What is an expression in math example?
An example of a mathematical expression with a variable is 2x + 3. All variables must have a coefficient, a number that is multiplied by the variable. In the expression 2x + 3, the coefficient of x is the number 2, and it means 2 times x plus 3.
What does it mean if an equation is open?
x is less than or equal to y. An equation or an inequality that contains at least one variable is called an open sentence. When you substitute a number for the variable in an open sentence, the resulting statement is either true or false. If the statement is true, the number is a solution to the equation or inequality.
