Idea of Math Filled Icon
This "math" icon consists of a perfect square divided in quarters perfectly, vertically and horizontally. In the upper left quarter is the perfect cross of the "addition sign." In the upper right quarter is the horizontal line of the "subtraction sign." In the lower left quarter is the two diagonal lines of the "multiplication sign." In the lower right quarter are the two vertical lines of the "equal sign."
This is a Math Filled icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,900 icons, all in the same style and quality.
