How to use the Desmos SAT calculator

The SAT exam features the built-in Desmos SAT calculator, a powerful testing aid that offers a wider range of functions than most standard handheld calculators. This advanced tool enables students to save valuable time and work more efficiently during the SAT Math section.

Be sure to review the guidance below to get comfortable with the exact calculator allowed and provided on both the SAT and PSAT. Developing a strong understanding of key SAT Math concepts is also crucial for correctly using the Desmos SAT calculator and maximizing its benefits as a helpful testing tool. Below are some top strategies for using the Desmos testing calculator effectively and confidently when tackling math questions on the SAT.

What calculators are allowed on the SAT?

The Desmos calculator can be accessed and used for both math sections of the SAT. The launch of the digital SAT in 2024 introduced a more streamlined test structure and new policies regarding the use of calculators. In previous versions of the SAT distributed on paper, handheld calculators were only allowed for one math section of the test. Today, students can use the online calculator provided by the College Board throughout the exam, allowing students to solve math questions more efficiently.

Tips and tricks for using the embedded Desmos calculator:

Tip 1: Use sliders

When you are given the task to evaluate constants, you may use the Sliders option to quickly see a range of different outcomes for that equation:

When you add a letter other than x or y, you should see this option:

Enter y = ax - 7

After clicking the “a” button, a graph with a slider will appear. This allows you to easily move the slider between a range of values.

You can also do this by clicking on the “a” variable in the equation and inputting the values that way. This will adjust it to the specific value you input.

Tip 2: Easily solve absolute value problems

When you are solving a problem that requires the absolute value, it is quite easy to solve in Desmos:

Try inputting a sample equation like this one: |𝑥 − 5| = 10

When typing this in, click on the keyboard icon.

Next, click on the absolute value symbol.

Now you can use the graphs and features to solve the equation!

Tip 3: Easily get fractions from decimals

If you are given a number in decimal form, you can change it to a fraction easily by clicking the fraction button.

Tip 4: Easily find the mean and median of a list

Finding the mean and median of a set of numbers in a timed problem can be a challenging task. Desmos has simplified the process, reducing calculation time. When you are given a set of numbers and are tasked with finding the mean and median, simply click on the Functions button and select the mean or median option to obtain the required numbers.

This can make some problems much easier and faster to solve. Definitely look out for opportunities to use this on the real test.
