In a work session with the wiris calculator various calculations grouped in blocks can be carried out. The calculation process steps are as follow:

  1. An expression for calculation is built using the keyboard or using the icons associated with the various commands.
  2. In each block as many expressions as desired can be entered. To add a new expression, following the expression where the cursor is located, use the key Enter (Carriage return).
  3. Evaluate an expression or block of expressions by clicking on the icon or the key Ctrl + Enter(Ctrl + (Carriage return).).
  4. The result is shown to the right of the original expression and separated by the arrow

To create more elaborate calculations, bear in mind the following points regarding page layout in wiris

  • A block can be added to the session with the icon on the Edit menu.
  • Whenever we evaluate (click on the icon or Ctrl + Enter), all expressions in the active block are calculated. The results are shown and a new empty block, which becomes the active block, is created below. The cursor appears in the active block.
  • The variables and calculations in one block are independent of the variables and calculations in all the other blocks.
  • To start a new work session, use the icon .
  • To save the current sesson, click on the icon and save the HTML page generated.

Return to wiris to try it out or see the following examples:

NOTE 1 Lower case and upper case letters are understood as different characters. Tan is not the same as tan.

NOTE 2 Parentheses only group, (1,2,3) is the same as 1,2,3.
