#Equivalent expressions code#

If that's right, and you make sure your float types are the same, then you should get either the same representation, or a representation which differs only in digits which don't actually matter (which you can check, with equivalent code to the above).

I don't know how to get Java to print a float so it can be read back in like this: I think it might be the %s format control. But you can confirm that these two representations are the same single-float: > (= 0.0026016448 0.0026016447) Note that the two implementations print different looking results in the single-precision case.

(eql (read-from-string (write-to-string x))Īnd now in one implementation (the first example is using single precision the second double, which is how CL should read these with default reader settings): > (f 1.001 1.0003) Then we can test the read-print consistency with (defun tsrp (x) Therefore, we can say that they are equivalent expressions. See why below: The two expressions have the same answer, 27. For example, and are equivalent expressions. Instructional IEP learning goal in Math, Expressions and Equations for students in grade 6 about Creating Equivalent Expressions and aligned to AAS.6.EE. They may look different but will have the same result if calculated. The default CL printer is (or should be) rather careful to print enough information that the float can be read back in and be the same to the one it printed. Equivalent Expressions Equivalent Expressions are expressions that have the same value. Chances are the numbers are actually the same. With the worksheet generator, you can control control the number of operations in the problems, the number of problems, workspace, border around the problems, and additional instructions.If you are using the same float types (singles or doubles for both), then what you are seeing is probably the different behaviour of the thing that prints the floats. Worksheets for evaluating expressions with variables Medium-level worksheet: expressions have two or three operations 8 problems per sheetĪll expressions have three operations 6 problems per sheet Very easy expressions – only one operation 12 problems per sheetĮasy expressions – two operations 8 problems per sheet Below, with the actual generator, you can generate worksheets to your exact specifications. Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them). Use these quick links to create some common types of worksheets for writing expressions.

For example, students would have to match that 2 + 5x + 3y + x + y is equal to 2(3x + 2y + 1).

This has the advantage that you can save the worksheet directly from your browser (choose File → Save) and then edit it in Word or other word processing program. A fun and different way of getting your students to practice identifying equivalent expressions This activity gets your students matching and simplifying equivalent expressions. To get the worksheet in html format, push the button " View in browser" or " Make html worksheet". You will have unlike terms on the right side, so you cant combine '6e' with '-ef'. 1) Move 'ef' across the equaly by subtracting it from both sides. To get the PDF worksheet, simply push the button titled " Create PDF" or " Make PDF worksheet". To solve the equation for 'd', you use the same techniques that you would use for any equation.

You will also be asked to write an expression and determine if two expressions are equivalent. After reading a story problem you will match it with an expression, or expressions, that represent that situation.

You can generate the worksheets either in html or PDF format - both are easy to print. These free equivalent expressions worksheets will help you prepare for your end of the year math exams. Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them). The answer key is automatically generated and is placed on the second page of the file.

The problems give the student the expression in words, such as the quotient of 7t and 5, the difference of x and 8, divided by 2, or the quantity 8 plus 2t, cubed, and ask the student to write a mathematical expression to match that.Įach worksheet is randomly generated and thus unique.
