This is the Matematyka icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
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."
