Math desmos scientific calculator  online free scientific/mathematical calculator
 AC = All Clear
 mc = Memory Clear
 m+ = Memory Plus
 m = Memory Minus
 mr = Memory Recall
 CE = Clear Entry
 √x = Square Root
 AC = All Clear
 e^{x} = exponent, raise e to the power x
 1/x or x^{−1} = A multiplicative inverse or reciprocal for a number x
 x² = Square
 () = Parentheses, instructs calculator to do this operation first
 y^{x} or x^{y} = y raised to the power x or x raised to the y
 y√x = parent function of a square root function is y = √x
 tan^{1} = The inverse of tangent is denoted as Arctangent or on a calculator it will appear as atan or tan^{1}
 cos^{1} = Is called acos or arccos
 sin^{1} = Inverse sine function or Sin^{1} takes the ratio, Opposite Side / Hypotenuse Side and produces angle θ. It is also written as arcsin
 ln = Log function is Ln(x) = Log(x)/Log(e)
 Rad = Radians
 Deg = Degrees
 e = E (or e) stands for exponent of 10
 RND = Gives a random number in (0,1)
 EXP = Stands for exponent(Click the Exp button which you will find in the left half of the calculator keyboard)
 ± = Both plus and minus math operations
Purpose of using free math desmos calculators?
Use this student calculator for math with addition, subtraction, division, and multiplication, scientific calculators include exponents, log, natural log (ln), trigonometric functions, and memory.
This website is quite easy only thing you have to do that just select number, operator, function, etc using the mouse or if you are using a mobile phone then touch the numbers and select your parameters like a number, operator, familiar function notation, many scientific calculators.

Scientific Calculator Basic Operations
The four basic operators. Each is used in the same way as a standard calculator: + (addition), – (subtraction), x (multiplication), and ÷ (division). Used to specify calculations in which certain operations have precedence.
Basic calculations are entered exactly the same order as they are written on paper, as demonstrated in the following activity. The calculator displays the calculation that you enter. When you press, the answer is displayed at the bottom right of the screen.
Fractions or decimals?
In Activity 1 you set up your calculators to use Math mode. In this mode, when the result of a calculation is not a whole number, it will be displayed as a fraction, such as, wherever possible.
To obtain the answer in decimal form, you need to press instead of, or you can toggle between the fractional and decimal outputs using the key.
Doing longer calculations using your calculators
The volume of wood (in cubic metres) contained in a log of length L metres with a distance around its middle of metres is given by the formula: V=L*D2/4Pi
Reusing a previous result
An alternative approach to our calculation is to calculate the denominator of the fraction first, and then divide the numerator by this.

Step #1: Enter the Number

Step #2: Press the Log Button

Step #3: Verify the Answer
Natural logarithms are the logarithms that have base “e,” and on most scientific calculator, these are represented by the “ln” button.
Using the calculators' memory
A variation on the above method is to break the calculation into two parts and use the memory functions of the calculator to store the result of the first part. The calculator memory is particularly useful when you want to calculate the values of several expressions that have a common part. This common part needs to be entered only once and its value reused several times subsequently. For example, rewriting the formula for the volume of wood contained in a log as.
Trigonometric ratios on your calculators
There are various different units in which an angle can be measured, degrees being one of the possibilities. Before using your calculator to find the values of the trigonometric ratios of angles measured in degrees, you need to ensure that it is set to use the correct units.
Logarithms on your calculators
The "Log" function on a graphing or scientific calculator is a key that allows you to work with logarithms.
Familiar function notation
You can used student works offline or the internet connection required for using these desmos calculators apps for teachers/students.
