This package offers command line tools to
- do exact calculations with fractions and integers (add, subtract, cancel)
- solve linear equation systems (Gauss alogrithm)
Usage without Installation
npx -p mathe add 1/2 1/4 // Output: 7/4 = 1 + 3/4 = 1.75
Usage with Installation
npm install -g mathe
add 1/2 1/4 // Output: 7/4 = 1 + 3/4 = 1.75
Further calculation instructions with fractions
subtract 12/4 3/2 // Output: 3/2 = 1 + 1/2 = 1.5
cancel 15/2 // Output: 15/2 = 7 + 1/2 = 7.5
mult -2/3 6/2 // Output: -2/1 = -2 = -2
add 1 2 1/2 2 -1/4 // Output: 21/4 = 5 + 1/4 = 5.25
mult 1/2 1/3 5 1/2 // Output: 5/12 = 0 + 5/12 = 0.4166666666666667

Usage examples for solving linear equation systems
Say you have a linear equation system like:
1x + 2y = 4
3x + 5y = 15
This can be solved by typing:
gauss "1,2=4" "3,5=15"
Output:
solution is:
x0 = 10/1
x1 = 3/-1
