Existing calculators have the inconvenience in having to check several times for having mistake in input. This transparent calculator drags over the numbers shown on the receipt or paper to make fast and accurate calculation. When the calculator is shaken, it is charged with LCD to become transparent as it is turned ON. If discharged, LCD becomes unclear to be turned OFF.
