	You use the A slide and D stator to square number. (A is a log-squared scale.) Simply position the reticule of number you want to square on the D stator and read the result off of the A slide. (Remember to properly estimate the proper decimal point for your result.)		You use the A slide and D stator to square number. (A is a log-squared scale.) Simply position the reticule of number you want to square on the D stator and read the result off of the A slide. Remember to properly estimate the proper decimal point for your result. '''Note''': the slide and stator must be aligned in order to calculate the square of a number.
