While it's not required by C#, this challenge apparently requires a space in addition to the comma separating the arguments. You might want to report this as a bug to Support.
Also, your top line seems to have a stray static
qualifier added in, but the line shown in context does not.

Implement the Subtract method so that the test passes. using System;
public class Calculator { public double Result;
public Calculator(double number)
{
Result = number;
}
public void Add(double number)
{
Result += number;
}
public void Substract(double number)
{
Result -= number;
}
}
using Xunit;
public class CalculatorTests { [Fact] public void Initialization() { var expected = 1.1; var target = new Calculator(1.1); Assert.Equal(expected, target.Result, 1); }
[Fact]
public void BasicAdd()
{
var target = new Calculator(1.1);
target.Add(2.2);
var expected = 3.3;
Assert.Equal(expected, target.Result, 1);
}
[Fact]
public void BasicSubtract()
{
var target = new Calculator(1.1);
target.Substract(0.2);
var expected = 0.9;
Assert.Equal(expected, target.Result, 2);
}
}

231,198 PointsYou should create a new question for a new topic, for several reasons:
- The "view challenge" button at the top is only correct for the first question.
- When you choose "best answer" it will be clear which question it answers.
- Others with similar problems might not be able to find the question and answer by title.
Also, be careful to quote your code correctly using the Markdown Cheatsheet.

231,198 PointsI'm not sure what you mean by "decided". It does not look like you have chosen a "best answer" yet.
I did find your new question and I also provided an answer there for you.
