This is also very easy, and follows the pattern of addition.

echo (math "37 - 12") will give the correct answer of 25

Floats will also work

echo (math "33.435 - 18.67") will give the answer 14.765

NB 

Just like addition, the parentheses are needed. The quotes are optional.

A negative quantity can result if this is the case

echo (math "37 - 82") will give a result of -45.

This will also work with floats

echo (math "37.67 - 82.48") will result in -44.81
