4/10/2023 0 Comments Equivalent expressions calculatorWhen two things are equal, they usually say they are equivalent. If you put the same variable value in equivalent expressions, you get the same value with each simplification. The equivalent expressions are the same expressions, although they may look slightly different. What is an equivalent variable expression? What is an equal expression?Įqual(expression, expression) Creates a binary expression that represents an equality equation. For example, if you replace x: = 3 with x + x + 4, you get 3 + 3 + 4, which decreases to 10, and if you replace it with 2x + 4, you get 2(3) + 4, which is also equal to 10. Two algebraic expressions are equivalent if they always return the same result when evaluated, regardless of the values you use for the variables. In this case, the two numbers are divisible by 2. If you were given the expression 6xy + 4x, you would have to invert it and remove the total numbers. You may need to analyze the equation to find an equivalent expression. Identify the factors that the parts of the equation have in common. How do you find the equivalent expression? 3) Finally, a new window displays the equivalent expression for the specified algebraic expression. ![]() 2) Now click the Submit button to get the equivalent expression. How to write an equivalent expression?ġ) Enter an algebraic expression in the input field. Example: multiplying by 3.3 (x 3y + 4) 3x 9y + 12 equals x 3y + 4. To make an equivalent expression, all you need to do is multiply the FULL equation by any number, and that equation will be equivalent. For example, the expressions y + y + y y 3y are equivalent because they refer to the same number independently of the number y. Here are the links to the two activities and a video overview that goes through some of the functionality of the fx-300ESPlus2 that is needed in the activities.How do you identify equivalent expressions? Determines when two expressions are equivalent (when both expressions refer to the same number, regardless of the value it replaces). Each activity has an application and then some practice problems. Both activities, as you will see, include standards, warm-up exploration questions, suggestions for student discussion and ways to extend. This allows them to get a better understanding about exponential rules and working with whole number exponents and bases. They use the calculator to store variable values and then use these as either the base or the exponent to try to create expressions that fit specific criteria. The second activity, The Variable Game, focuses on exponential expressions, and helping students apply properties and write exponential expressions with given parameters. The calculator is used as a verification tool, where students use stored values for given variables that then allow them to check that different expressions yield the same result. ![]() The first activity, It’s All the Same, is about using properties of operations (associative, commutative, distributive) to explore equivalent expressions. Both these activities focus on expressions with a goal of understanding what expressions are, equivalent expressions, the role of variables. Today I am going to share two activities that utilize the fx-300ESPlus2, though you could use these with any scientific calculator from Casio (or graphing for that matter). equations, expressions, inequalities, and statistics. ![]() This week I am going to be showing some of the capabilities of scientific calculators that I don’t think many people realize they can do – i.e. ![]() If we are thinking about equity and getting technology in the hands of students, scientific calculators are powerful tools that can support math discovery and exploration (except graph, though the fx-991EX even does that!) and are really inexpensive (between $10 – $20).
