See more:

int divide = 100;
       string strSQLconnection = ("Data Source");
       SqlConnection sqlConnection = new SqlConnection(strSQLconnection);
       sqlConnection.Open();
       SqlCommand sqlCommand = new SqlCommand("SELECT Discount * UnitPrice /" + divide + "FROM Items.Product where ProductName LIKE" + "'" + item3 + "'", sqlConnection);
       decimal answer = Convert.ToDecimal(sqlConnection.ExecuteScalar());

ExecuteScalar is seriously giving me a headache it gives me the following error Error 5 'System.Data.SqlClient.SqlConnection' does not contain a definition for 'ExecuteScalar' and no extension method 'ExecuteScalar' accepting a first argument of type 'System.Data.SqlClient.SqlConnection' could be found (are you missing a using directive or an assembly reference?

i tried to solve this but im out. HELP

You are trying to execute the ExecuteScalar on your connection instead of your command. You need to change that line to be:

C#

sqlCommand.ExecuteScalar()

To add to this, I would recommend that you change your naming conventions to be a bit clearer. For example, you have strSQLconnection representing the connection string while sqlConnection represents the SQL Connection object. That is confusing. It also doesn't follow good guidelines for naming conventions, which will cause you problems down the road. I would suggest something like connectionString for your connection string and sqlConnection for your SQL connection. That makes it a bit easier to understand what the job is for each.
