Hi,
this is my code:
var a = 5
var b = 8
var e = 12
var d = 33
var k = 100
-a + -b - -e + -d
The console displays an error message in the 7th line
Playground execution failed: error: MyPlayground 5.playground:4:14: error: expression was too complex to be solved in reasonable time; consider breaking up the expression into distinct sub-expressions
-a + -b - -e + -d
~~~~~~~~~^~~~
Why?
