Most formulas and math equations come as floating objects. Such objects cannot be read by a screen reader and are therefore, inaccessible. To avoid inaccessible content being sent, we must find a more accessible solution for how to write our formulas.
...
| Warning |
|---|
This equation is a floating object and spreads out over multiple cells. This is inaccessible, and overall does not look presentable.  |

...
One more rule to follow is to make sure your individual formulas are in one cell.
...
| Warning |
|---|
The formulas are typed in one cell and interferes with the cell next to it. This would be very hard for a person using a screen reader to understand.  |
...
| Tip |
|---|
The formula is now in one cell and all of the information is given with a text description.  |
Section 8.2: Math Equations without Floating Objects
The best way to create an equation that is accessible is to type out the whole equation without symbols.
...
| Warning |
|---|
These equations are written out in the traditional way. Screen readers would not be able to read the equations the way they are written. This table is therefore, inaccessible to many readers.  |
...
| Tip |
|---|
These formulas are all written in text form. Now screen readers can read the information to the reader without too much risk of errors.  |
Section 8.3: Excel Functions
Most Excel functions are accessible for readers, and can be read by both JAWS and NVDA. However, the software will only read the formula character by character. This process can take a long time to complete and can be very time consuming for the students. To avoid this issue, type in the name of the formula and an abbreviation above the cell containing the results.
...
| Warning |
|---|
This example shows a function calculating the sample standard deviation for some data. Though this is accessible, it does not contain the name of the function or abbreviation.  |
...
| Tip |
|---|
This example shows a function with a name and abbreviation. This is the best way to display functions.  |
