\![\"\"](\"/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=ec03a44b16620923e86ac5800b3da624.png\")
(Divide: ![\"\"](\"/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=f5f42819068583a18d62f1e192defce1.png\")
)
Next operation is subtraction
