This is a very simple icon made up on just a single horizontal line. The line is rather thick, however, and it's meant to represent the minus sign that's often seen in mathematics classrooms.
This Subtract icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office
, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,700 icons, all in the same style and quality.
