Usage

Class Expressions

Execute the below code to obtain an array of expressions coded for HTML ready to display in browser.

$expressions = (new Expressions($parameters))->getExpressions();

Example result

1<sup>4</sup>&frasl;<sub>6</sub> + (<sup>4</sup>&frasl;<sub>8</sub> + 2.1 + 6 + <sup>5</sup>&frasl;<sub>10</sub>) * <sup>3</sup>&frasl;<sub>4</sub> =
<sup>5</sup>&frasl;<sub>10</sub> * <sup>5</sup>&frasl;<sub>5</sub> * (2<sup>1</sup>&frasl;<sub>3</sub> + <sup>1</sup>&frasl;<sub>6</sub> - 10) - 10 =
5 - 6 * (<sup>4</sup>&frasl;<sub>8</sub> - 6) + 4 =
<sup>6</sup>&frasl;<sub>4</sub> - (6 : (-<sup>6</sup>&frasl;<sub>9</sub>) - 2) =

giving the following display

1⁴⁄₆ + (⁴⁄₈ + 2.1 + 6 + ⁵⁄₁₀) * ³⁄₄ =

⁵⁄₁₀ * ⁵⁄₅ * (2¹⁄₃ + ¹⁄₆ - 10) - 10 =

5 - 6 * (⁴⁄₈ - 6) + 4 =

⁶⁄₄ - (6 : (-⁶⁄₉) - 2) =

Class internal variables are self documented. The defaults can be changed passing new values to the class constructor as an array of pairs "variableName" => variableValue.

Note: : (colon) stands for division operator symbol.
