Desmos Test Mode 7.17.0

These are limited versions of the Desmos Calculators that adhere to exam requirements. To prepare for specific state or national assessments, simply select the corresponding test from the app's menu. To determine whether Desmos is allowed for your test, visit www.desmos.com/testing.

If you prefer to use the full, unrestricted versions of the calculators, you can download the Scientific or Graphing Calculator apps or visit www.desmos.com.

At Desmos, our vision is a world where math literacy is universal and mathematics is accessible and enjoyable for all students. To achieve this, we have created simple yet powerful calculators that are both intuitive and visually appealing. Best of all, they are completely free!

Graphing Calculator Features

• Graphing: Plot polar, Cartesian, and parametric graphs with unlimited expressions. No need to enter expressions in y= form.
• Sliders: Interactively adjust values to enhance understanding or animate parameters for visualizing their impact on the graph.
• Tables: Input and plot data or create an input-output table for any function.
• Statistics: Utilize regressions to find the best fit lines or curves for your data.
• Zooming: Scale axes independently or simultaneously through pinch gestures or manual window size adjustments.
• Points of Interest: Discover maximum and minimum values, intercepts, and intersection points by touching a curve. Tap these points to see their coordinates. Trace along a curve to observe coordinates changing under your finger.

Scientific Calculator Features

• Variables: Assign values to variables for use in other expressions. All work is stored in the expressions list, allowing you to compute a value once and use it in multiple places simultaneously. Use the "ans" key, which always holds the value of the previous expression.
• Arithmetic: Perform basic operations as well as exponentiation, radicals, absolute value, logarithms, rounding, and percentages.
• Trigonometry: Evaluate trigonometric functions and their inverses using radians or degrees for angle measure.
• Statistics: Calculate mean and standard deviation (sample or population) of a data list.
• Combinatorics: Count combinations and permutations, and calculate factorials.

Four-Function Calculator Features

• Simple and Beautiful: Essential operations such as addition, subtraction, multiplication, division, and square roots done right.
• Multiple Expressions: All previous work remains visible on the screen unlike many four-function calculators. The "ans" key always holds the value of the previous computation and updates automatically, eliminating the need to remember or copy results.
