private async Task<Document> ChangeToOneLiteral(InvocationExpressionSyntax ex, Document document, CancellationToken cancellationToken)
{
var literal1 = ex.GetLiteralExpression();
if (literal1 == null) return document;
var literal2 = ex.GetLiteralArgument();
if (literal2 == null) return document;
var x = int.Parse(literal1.Token.ValueText);
var y = int.Parse(literal2.Token.ValueText);
var newValue = 0;
switch (ex.GetMemberName())
{
case "Add": newValue = x + y; break;
case "Sub": newValue = x - y; break;
case "Mul": newValue = x * y; break;
