3. Let's do some math

[mladencikara]

I have put: (ns math-operations)

(+ 1 2 3)

(println (+ 1 2 3)) (+ 5 (* 5 (- 7 2 1)))

In console and when I run it returns:

3. instruction failed.

@mladencikara thanks for reaching out! you need to print this expression: (+ 5 (* 5 (- 7 2 1))) so code will end up like this:

(ns math-operations)

(+ 1 2 3)

(println (+ 1 2 3))

(println (+ 5 (* 5 (- 7 2 1))))
