Figure 8.13. This is a table of Boolean algebra theorems. They are written using the notation indicated in the table above but they will be read as the table above says they should be spoken.

0 and 0 = 0. 0 and 1 = 0. 1 and 0 = 0. 1 and 1 = 1. eh and 0 = 0. eh and 1 = eh. eh and eh = eh. eh and not eh = 0.

0 or 0 = 0. 0 or 1 = 1. 1 or 0 = 1. 1 or 1 = 1. eh or 0 = eh. eh or 1 = 1. eh or eh = eh. eh or not eh = 1.

0 X-or 0 = 0. 0 X-or 1 = 1. 1 X-or 0 = 1. 1 X-or 1 = 0. eh X-or 0 = eh. eh X-or 1 = not eh. eh X-or eh = 0. eh X-or not eh = 1.

eh and b = b and eh. eh or B = B or eh. eh X-or B = B X-or eh.

eh and quantity B or C close quantity = quantity eh and B close quantity, or, open quantity, eh and C, close quantity.

eh or quantity B and C close quantity = quantity eh or B close quantity, and, open quantity, eh or C, close quantity.

Not the quantity eh or B close quantity, = not eh and not B.

Not the quantity eh and B close quantity, = not eh or not B.
