Free Math App is an excellent tool for seamlessly grading student work without timely preparation. Students are able access any mathematical symbol many word processing tools lack, enabling them to display their math work accurately and quickly.

I would just like to compliment you guys on the work you've been doing with the website. This has been a life saver. All of my classes are using this and some students have had to quarantine but they can still work on the HW and submit it.

Your site has made these difficult times of distance learning so much easier to manage as a teacher. I've raved about your site to several teachers and we're using it in all of our middle and high school classes.
## Use All of Your Existing Materials

## Embrace Visual Learning

## No Accounts Or Downloads Required

## Get Involved

## Great for Many Areas of Math

### Algebra

### Calculus

### Physics

meaningfully and efficiently.

Students can start with a blank Free Math document, copying down and working through problems just as they would in paper notebooks.

Students save their work as a file and submit it through an LMS in response to an assignment.

Complete solutions are shown, grouped by similar final answer.

You can award partial credit and give feedback to students that need help.

You don't need to type in an answer key, Free Math just provides an organized view of all student work.

Your site has made these difficult times of distance learning so much easier to manage as a teacher. I've raved about your site to several teachers and we're using it in all of our middle and high school classes.

You can assign problems from anywhere including a textbook, worksheet or digital document like a Google Doc, Microsoft Word file or a PDF.

The flexible grading experience means you don't need to convert your materials. Students just reference problems from anywhere and produce digital work that can be reviewed in Free Math immediately with no setup ahead of time.

Students can add digital drawings and graphs to their assignments, or paste an image from another site like Desmos or Geogebra.

When writing on paper works better for some students, they can quickly snap a picture of their notebooks with their webcam.

The entire experience runs right in your web browser.

Direct integration is provided for Google Drive and Classroom, including gradebook integration.

For other LMSes and cloud storage providers, assignments and grading sessions save directly from the browser to files in your downloads folder and from there they can be uploaded to any service you use for your class.

The files can be collected in any LMS, downloaded all together and loaded for grading. After grading, your LMS also easily provides an individual feedback file to each student.

Help us build our revolution, Free Math has already been used by tens of thousands of students and teachers
to help improve feedback and discussion in their classes.

$\frac{1}{x-4}+\frac{2}{x^2-16}=\frac{3}{x+4}$

$\frac{1}{x-4}+\frac{2}{\left(x-4\right)\left(x+4\right)}=\frac{3}{x+4}$

$\frac{1}{x-4}\cdot\left(\frac{x+4}{x+4}\right)+\frac{2}{\left(x-4\right)\left(x+4\right)}=\frac{3}{x+4}\cdot\left(\frac{x-4}{x-4}\right)$

$\frac{1\left(x+4\right)}{\left(x-4\right)\left(x+4\right)}+\frac{2}{\left(x-4\right)\left(x+4\right)}=\frac{3\left(x-4\right)}{\left(x+4\right)\left(x-4\right)}$

$x\left(t\right)=v\cos\left(\theta\right)t=20\cos\left(40\right)t=15.3t$

$y\left(t\right)=y_0+v\sin\left(\theta\right)t-\frac{9.8t^2}{2}$

$y\left(t\right)=1+20\sin\left(40\right)t-4.9t^2$

$y\left(t\right)=1+12.9t-4.9t^2$

$v_y\left(t\right)=v\sin\left(\theta\right)-9.8t$

$v_y\left(t\right)=12.9-9.8t$

$\max\ height\ at\ v_y\left(t\right)=0$

$12.9-9.8t=0$

$-9.8t=-12.9$

$t=\frac{-12.9}{-9.8}=1.3$
