The expression is ![\"\"](\"/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=959398bd3b1adb36901a6f925630f29d.png\")
.
Round to the nearest whole number then multiply.
\4.2 rounded to the nearest whole number is 4.
\29.3 rounded to the nearest whole number is 30. \ \
