A multi-colored plastic abacus, designed for educational purposes, is centrally positioned on a dark, textured fabric surface. The abacus features a blue plastic frame with pink plastic corner accents. The top horizontal bar displays embossed numbers 1 through 10. The left vertical bar is embossed with numbers 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100. The right vertical bar presents embossed uppercase letters A, B, C, followed by lowercase letters a, o, e. The bottom horizontal bar includes embossed mathematical symbols: plus (+), minus (-), multiplication (x), and equals (=). A piece of clear adhesive tape is visible over the multiplication symbol. The abacus contains ten horizontal metal rods, each holding ten plastic beads, totaling 100 beads. All beads are uniformly pushed to the right side of their respective rods. From top to bottom, the bead colors are light green, magenta, black, orange, light blue, light green, light blue, black, orange, and magenta. The dark, textured fabric background, possibly upholstery, shows a dark, rounded button or stud partially visible in the upper-left quadrant.
