Dot Operators for Logical And
Jan 12, 2025 12:59

My logic textbook this semester uses a dot for “and” instead of an ampersand. Unfortunately, the center dot in LaTeX is too small to be easily legible. I managed to increase the size of the LaTeX cdot by using the bm package and renewing the command to \bm{\cdot}. In some cases, such as social media and the web, it’s easier to use a unicode symbol. Here are the obvious options:

Dot Operator ()

(A ⋅ B)

Bullet Operator

(A ∙ B)

Bullet

(A • B)

The bullet seems slightly more legible. Here’s how it looks in a more complex formula:

I don’t see any downside to using the bullet.
