11,193 PointsBummer! Assert.Equal() Failure, Expected: 0.9, Actual: 0.9 What am I doing wrong??
It says to implement the Subtractr method so that the test passes. It seems to pass just fine, but it it doesn't let me continue.

Treehouse TeacherHi there! You're really close, but you have 2 typos and a missing argument. Twice you've misspelled "Subtract" as "Substract". Note the extraneous "s" in your version. Those are found in these lines:
// This one
public void Substract(double number)
// And this one
target.Substract(0.2);
Also, you need to pass in the integer 1 at the end of your assertion here:
Assert.Equal(expected, target.Result, 1);
Hope this helps!
edited to change the word "parameter" to "argument" to be semantically correct
