$13 · INCREDIBLE SOLAR-POWERED CALCULATOR

THIS IS A CALCULATOR SO AMAZING, IT NEEDS TO BE DESCRIBED IN ALL CAPS SO THAT YOU CAN FEEL THE POWER!! IT CAN ADD, SUBTRACT, MULTIPLY AND DIVIDE! DO PERCENTAGES, SQUARE ROOTS, OR MORE COMPLICATED TASKS THAT INVOLVE THE "MEMORY" FUNCTION THAT EVEN I, A CHILD PRODIGY, COULD NEVER FIGURE OUT! IF THATS NOT ENOUGH, USE THE BUILT IN RULER ON THE SIDE TO MEASURE THINGS UP TO 14 CENTIMETRES!!!! STILL USE A MINI THREE RING AGENDA?? NO PROBLEM, HOLES ON THE SIDE ALLOW YOU TO CLIP IT IN THERE!!! (Might need a battery change. Not included. Unless you're a nice person.)
