Instruction for MathEditor.com

Formulas can be written very fast in IT format.

Example

You enter the upper square above:	Half of 10 is 10/2
Then click or press Enter.
The flags and the text will disapear and automatically will be written:	Half of 10 is   10   2   =   5

Open MathEditor.com   and try !

MathEditor.com can be operated directly online from the website and can also bedownloaded to your own computer and used offline.

Click button explanation
If you click on a click button, the procedure is as described below.

	MathEditor will be downloaded as a ZIP file named MathEditorOffline. The file is usually stored in the Downloads folder. On a PC, right-click in the file and select "Extract All ...". A folder with the same name will be created and there is a file named MathEditorOffline in this folder. Clicking on this file will enable MathEditor without using the Internet.
	You can choose whether you want to use decimal point or a decimal comma. with decimal point, commas may not appear in calculation expressions, and with decimal comma, points may not appear in calculation expressions.
	Calculation will be made. This facility can also be accessed by pressing "Enter" (line breaks).
	The text in Math format is printed or saved as a PDF file. If you want to save, change the printer to "Save as PDF". If you want to save the text in IT format, just click:   .
	Here you can send the IT text by e-mail. The recipient can view the math in a mathematical format by copying to MathEditor. It can often make sense to send yourself and then save the IT text for further editing later.
	Another website will open with MathEditor. It is useful to solve several tasks.
	Some characters are displayed, which can be inserted at the end of your text with one click.

Mathematical expressions
Mathematical expressions are written in IT format, which is very fast.

	Format of the math	IT-Format
Plus	2 + 3	2+3	There is no difference
Minus	5-3	5 - 3	There is no difference
Multiplication	2⋅3 2 × 3	2*3	2·3   when decimal point is used   and   2×3   and 2 × 3 when   decimal point is used.
Division	6     3	6/3
Superscript	5²	5^2
Subscript	x2	x_2
Square root	√9	sqrt(9)
Root	³√7	root(3;7)	Note: Semicolon
!	3! = 6	3! = 6	There is no difference
Pi    π	π	pi()	π = 3,14 (rounded)
Euler's number   e	e	e()	e = 2,718 (rounded)
Logarithm	Log(10)=1	Log(10)=1	There is no difference
Natural logarithm	Ln(e)	Ln(e())
Natural exponential function	exp(e) = 1	exp(e()) = 1
Cosine	Cos(60°)	cos(60) Cos(60°)	Both options are available in the  IT format can be used
Sinus	Sin(30°)	sin(30) Sin(30°)	Both options are available in the  IT format can be used
Tangent	Tan(45°)	tan(45) Tan(45°)	Both options are available in the  IT format can be used
The inverted cosine	Cos-1(0) = 90°  arcCos(0) = 90°	Cos^-1(0) = 90  arcCos(0) = 90
The inverted sinus	Sin-1(1) = 90°  arcSin(1) = 90°	Sin^-1(1) = 90  arcSin(1) = 90
The inverted tangent	Tan-1(1) = 45°  arcTan(1) = 45°	Tan^-1(1) = 45  arcTan(1) = 45
Σ   Sigma	3 Σ 2j = 12 j=1	Sigma(j=1;3;2j) = 12	Note: Semicolon.  After the sigma comes automatic  line break in the Math text.
Functions      You can define functions yourself      with names from a to z and from A to Z.      Function names are case-sensitive.      Ie by functions distinguishable      uppercase and lowercase.      For example, type:      g(t)=2t      G(t)=t^2           (t^2=t²)      g'(t)=2      When you define a function, you often      by automatic calculation also will get      the derivative and antiderivative,      as you can use immediately without further ado.      If you want to see the function expression,      just enter for example: G(t)	10+g(3) = 16	10+g(3) = 16

Bold, lowered, raised and colored font
Bold are obtained by <<bold >> , Example: <<bold >> a=5 becomes: a = 5
Bold printed shifts are indicated by < nobold >> finished or at the end of the text.
Colors are obtained by <<red>>, <<blue>>, <<brown>>, <<green>> or <<black>>. The color continues the text or until new color is selected.
Finally, font bold also appears after the text "  = "(2 spaces and an equal sign). Therefore, the calculation results are printed in bold.
Lowered font is available by   _   and automatically terminates appropriately.     Example:   b_2*5   becomes  b₂×5   and  b_(2*5)  becommes  b_(2×5)
Raised writing, eg exponents, is available by  ^  and terminated automatically in appropriate manner    Example:  5^2*5  becomes  5²×5  and  5^(2*5)  becomes  5^(2×5)

Insert Table/Herringbone
This is done by entering   ::  (2 colons)  after each table element.
Numbers and letters can be inserted in the table, but no calculations.

Angles
Angles are specified in degrees.
It is most beautiful to write ° .  eg: Sin(30°).  
The icon °  will often be supplied automatically.  Anyway you can get   °   (and also ∠ icon)   by clicking
Futhermore you on a PC can get ° by holding down the Alt key and pressing 248 on the numeric keypad.

Facit can be remembered
Facit can be remembered in a letter, for example, by typing the following: b=2*3
For example, you can write down the following: b+1 and the value is 7
There is no distinction between uppercase and lowercase letters.

percent
% can be included in the calculation. Example: 4*20% = 0.80
