I have the code snippet exposed below:

var calcularSoma = function (primeiroValor, segundoValor) {
var soma = primeiroValor + segundoValor;
if (soma < 10) {
	console.log(soma, "Unidades.");
	return soma;
} else if (soma < 100) {
	var restoUnidade = soma % 10;
	var dezena = soma / 10;
	if (restoUnidade == 1 && dezena <= 1) {
		console.log(dezena, "Dezena. e ", restoUnidade, "Unidade");
	} else {
		console.log(dezena, "Dezenas. e ", restoUnidade, "Unidades");
	}
	return soma;
} else if (soma < 1000) {
	var centena = soma / 100;
	console.log(centena, "Centenas.");
	return soma;
} else {
	var milhar = soma / 1000;
	console.log(milhar, "Milhar.");
	return soma;
}
}

calcularSoma(5, 10);

1. What I intend is to display the result in the plural if the values contained in the variables are greater than 1. I will implement the conditions below, at the moment I need to first understand which implementation will represent the logic exposed.

2. I need to format the displayed value, in this example the value 1.5 Dezenas e 5 Unidades. (plural of Unit is displayed, since the rest was greater than 1), I wanted to display something like: 1 Dezena e 5 Unidades. / p>

3. Here I used if(restoUnidade == 1 && dezena <= 1) because in this example above the value of the tens variable in thesis is greater than 1, although it is a decimal.

P.S.: If possible tell me how best to expose the question, first the following code of the doubts (as exposed in this post), or the first questions followed by the code?

When you see me you need to add some more ifs .

The problem can be in if (restoUnidade == 1 && dezena <= 1)

I do not quite understand what you want, but see if that helps. Modify this snippet in the code:

else if (soma < 100) {
  var restoUnidade = soma % 10;
  var dezena = soma / 10;
  if (restoUnidade == 1) {
    if (dezena <= 1) {
      console.log(dezena, "Dezena. e ", restoUnidade, "Unidade");
    } else {
      console.log(dezena, "Dezenas. e ", restoUnidade, "Unidade");
    }
  } else if (dezena > 1) {
    console.log(dezena, "Dezenas. e ", restoUnidade, "Unidade");
  } else {
    console.log(dezena, "Dezena. e ", restoUnidade, "Unidade");
  }
  return soma;
}
