An illustration of an abacus. It is a rectangular wooden frame with six rows and six columns. Each row has a different color - blue, yellow, orange, and red. The blue row is on the top row, the yellow row is in the middle row, and the red row is at the bottom row. The orange row is slightly larger than the blue row and is slightly smaller than the red one. The abacus appears to be empty, with no other objects or decorations visible.
