In order to view our math worksheets, you need to have a pdf viewer installed in your browser. Most modern browsers already have a PDF reader/printer included. For offline viewing, you might want to install Adobe Reader, Foxit or something similar.

Recommended Browsers

The Chrome browser includes its own built-in PDF reader. To print or save, right-click anywhere on the PDF preview and choose "Print" or "Save as". There is also a menu with print and download icons that appears when you move your mouse over the PDF. We highly recommend using the Chrome browser when visiting Math-Drills.com.

The Opera browser includes the same built-in PDF reader as Chrome; it looks slightly different, but has the same great interface and functionality.

The Safari browser is the best way to view PDF math worksheets on Apple computers and devices.

The Edge browser (Windows 10) includes a built-in PDF reader. To save a PDF math worksheet, right-click and choose "Save as". Printing requires an extra step. Open the math worksheet in its own window by clicking on the "Open" button. Access the "More actions" menu by clicking on the 3 dots (ellipsis) near the top right of the browser and select "Print".

The Firefox browser includes its own built-in PDF reader. Unfortunately, it doesn't print special characters very well, and there are many that are used on our math worksheets. Please see question #10 for a solution. To print or save, select the print or download buttons. If you do not see these buttons, open the "Tools" menu (located top right and looks like a guillemet: ») and choose "Print" or "Download". The lack of right-click print and save options leaves Firefox as a mediocre choice for navigating Math-Drills.com.

Internet Explorer requires a plugin such as Adobe Acrobat. If you do use Internet Explorer and have the Adobe Reader plugin, you can right-click on the PDF preview to print and use the hover menu to print and save. The Adobe Reader plugin, however, may not work properly in Internet Explorer.

To print from mobile devices, tap on "open the PDF math worksheet." If you have set it up, you will be able to send the math worksheet to AirPrint printers (Apple devices), Google Cloud Printers (Android devices) or another wireless printer or internet based printing service. For Android users, you may want to install the Adobe Reader app before tapping on the image.


In general, the answer keys are on the second page of the PDF math worksheet. For "All" versions, the answer keys are located on every second page. There are some exceptions for worksheets that do not require answer keys or for some special worksheets where the PDF documents are more than two pages long.

If you are using a desktop computer, you can view the answer keys by scrolling within the frame that contains the PDF worksheet. You can also use the "Open" button to view the PDF file full screen then scroll down to the answer key. If you are using a mobile device, you will definitely have to use the "Open" button since most mobile browsers do not allow PDF files to be embedded in a web page.

The built-in PDF reader in the Firefox browser has never worked properly for printing all of our worksheets. It has trouble with some special characters, including simple things like subtraction signs. If you insist on using Firefox, you can disable the built-in PDF reader and use something like Adobe Acrobat instead. Please follow these steps (hold down the CTRL key and click with your mouse to open all three links in new tabs):

  1. Install Adobe Acrobat You will probably be given some "Optional offers." Uncheck the optional offers. Click on the "Install Now" button and follow the rest of the instructions. There is no cost for this software.
  2. Disable the built-in PDF reader Choose "Use Adobe Acrobat (in Firefox)."
  3. Allow Adobe Acrobat to activate Look for the "Enable the PDF plugin" section in the linked help document. Make sure you set the Adobe Reader plugin to "Always Activate."
