This was a little confusing as I didn’t know where to add ‘Math.Floor(Math.Sqrt(Math.Abs(number)));’ (Step 4).
At first, I was trying to put it into the Math.Floor for numberTwo and tried a couple of different things before I realised that the Math.Foor is also in the double!

Could do with a little more clarity here to specify further where Math.Abs() should go. I worked it out eventually, which I suppose is positive for an aspiring coder!

using System;

namespace LowestNumber
{
  class Program
  {
    static void Main(string[] args)
    {
      // Starting variables 
      int numberOne = 12932;
      int numberTwo = -2828472;

      // Use built-in methods and save to variable 
			Math.Sqrt(numberOne);
      Math.Floor(Math.Sqrt(numberOne));
      double numberOneSqrt = Math.Floor(Math.Sqrt(numberOne));

      // Use built-in methods and save to variable 
			Math.Sqrt(numberTwo);
      Math.Floor(Math.Sqrt(numberTwo));
      double numberTwoSqrt = Math.Floor(Math.Sqrt(Math.Abs(numberTwo)));

      // Print the lowest number
			Console.WriteLine(Math.Min(numberOneSqrt, numberTwoSqrt));
      

    }
  }
