=== Subtraction ===
To subtract, you also use the linear slides, L and L. Position the reticule over the minuend on the lower L slide. Without moving the reticle, position the upper L slide so that the subtrahend is also under the reticle. Read the difference from the lower L slide.
'''Example:''' 3.2 – 2.1 = 1.1
