There are quite a few options how to calculate with Bash in OSX terminal but for reference I'd like to mention just several of them which can be used as a baseline.
echo "2 * 2" | bc
echo "scale=3; 1000/52 | bc" - will output result + 3 digits after comma
bc <<< "100 / 3"
bc -l <<< "sqrt(5)" (scale(3.3) - number of digits after comma, length(100) - number of digits)
awk "BEGIN {print 33 * 33}"
echo "2 * 2" | bc
echo "scale=3; 1000/52 | bc" - will output result + 3 digits after comma
bc <<< "100 / 3"
bc -l <<< "sqrt(5)" (scale(3.3) - number of digits after comma, length(100) - number of digits)
awk "BEGIN {print 33 * 33}"
