Project Algebra and Geometry Algebra and Geometry are easy. Here is an equation. Fill in the empty squares and solve the equation. F stands for the number of faces, C for the number of corners and E for the number of edges for a shape. For a cube F = 6. Could anything be easier? When you have worked out F, C and E for a shape you can solve the equation.
F + C – E = ?
