About Entering Math Characters

When you type a character string in a MathML element, Amaya parses the string and automatically generates the elements mo (operator), mn (number), mi (identifier), and mtext.

For example, to enter the formula x=2a+b:

  1. If you are not in a mathematical expression, choose Math > New formula (math) from the Types menu.

  2. Type this sequence of 6 characters: x=2a+b

Use the Structure view to display the following structure generated by Amaya:

<mi>x</mi><mo>=</mo><mn>2</mn><mi>a</mi><mo>+</mo><mi>b</mi>

If the result is not exactly what you want, select the characters that were misinterpreted and change their type with one of the commands such as Plain text (mtext), Identifier (mi), or Number (mnmo) from the Math submenu of the Types menu.

When entering brackets as in the following expression:

f ( x ) = 1 x

typing the sequence f(x)= would lead to:

f ( x ) = 1 x

Instead, choose Math > Parentheses from the Types menu or select the Parentheses option on the Maths palette to enter the parentheses properly.
