I put a comment on the code. There are just some incomplete words, just for the typing. However, everything okay for my reading. Gonna leave for another people to check more.

Fixed

Mr-Saxobeat

It was a good translation!
Please, would you follow the suggestions? And then finish the translation :D
Thanks!

+# Operadores

-We know many operators from school. They are things like addition `+`, multiplication `*`, subtraction `-`, and so on.
+Nós aprendemos muitos operadores na escolas. Alguns deles são adição `+`, multiplicação `*`, subtração `-` e assim por diante.


([] - delete; {} - add, change)

"... operadores na escola[s]."

- *An operand* -- is what operators are applied to. For instance, in the multiplication of `5 * 2` there are two operands: the left operand is `5` and the right operand is `2`. Sometimes, people call these "arguments" instead of "operands".
- An operator is *unary* if it has a single operand. For example, the unary negation `-` reverses the sign of a number:
+- *Um operando* -- é um valor onde os operadores são aplicados. Por exemplo, na multiplicacao  `5 * 2` há dois operandos: o operador da esquerda é  `5` e o operador da direita é `2`. Às vezes, pessoas os chamam de "argumentos" ao inves de  "operandos".
+- Um operador é *unário* se ele tem um único operando. Por exemplo, o negativo unário  `-` reverte o sinal de um numero:


"... o unário negativo..."
Because, "... o negativo unário..." sounds like "negativo" is an name, while it's a adjective.

Mr-Saxobeat · 2019-10-23T20:57:15Z

1-js/02-first-steps/07-operators/article.md

    x = -x;
    */!*
-    alert( x ); // -1, unary negation was applied
+    alert( x ); // -1, o negativo unário foi aplicado


"o unário negativo..."

I believe that "negação unária" would be better in that case.

Mr-Saxobeat · 2019-10-23T20:59:26Z

1-js/02-first-steps/07-operators/article.md

    ```js run no-beautify
    let x = 1, y = 3;
-    alert( y - x ); // 2, binary minus subtracts values
+    alert( y - x ); // 2, binário menos subtrai valores


Here you writed the correct order of the terms "binário menos", like you need to do on the comments above.

Mr-Saxobeat · 2019-10-23T21:01:10Z

1-js/02-first-steps/07-operators/article.md

    ```

-    Formally, we're talking about two different operators here: the unary negation (single operand: reverses the sign) and the binary subtraction (two operands: subtracts).
+    Formalmente, nós estamos falando sobre dois operadores diferentes aqui: o negativo unário (único operando: reverte o sinal) e o negativo binário (dois operandos: subtrai).


"... o unário negativo..."

"... o binário [negativo] (subtração)..."

Mr-Saxobeat · 2019-10-23T21:05:42Z

1-js/02-first-steps/07-operators/article.md

+Veja, não importa se o primeiro operando ou o segundo é uma string. A regra é simples: se um operando é uma string, o outro é convertido em uma string também.

-However, note that operations run from left to right. If there are two numbers followed by a string, the numbers will be added before being converted to a string:
+Entretanto, note que operatação são executadas da esquerda para direita. Se há dois números seguidos por uma string, os número serão adicionados antes e então convertidos para uma string:


"...note que (as) [operatação] (operações)..."

"...[adicionados] (somados)..."

Mr-Saxobeat · 2019-10-23T21:11:38Z

 ```

-String concatenation and conversion is a special feature of the binary plus `+`. Other arithmetic operators work only with numbers and always convert their operands to numbers.
+String concatenação e conversão é uma característica especial do binário mais `+`. Outros operadores aritméticos funcionam apenas com números e sempre convertem seus operandos para números.


"Concatenação e conversão de string..."

Mr-Saxobeat · 2019-10-23T21:12:23Z

1-js/02-first-steps/07-operators/article.md

+## Conversão numérica, unário +

-The plus `+` exists in two forms: the binary form that we used above and the unary form.
+O mais `+` existe de duas formas: a forma binária que usamos acima e a forma unária.


"... existe [de] (em) duas formas..."

Mr-Saxobeat · 2019-10-23T21:14:36Z

 ```

-It actually does the same thing as `Number(...)`, but is shorter.
+Na realidade faz a mesma coisa que `Number(...)`, mas é mais curto.


"... [mas] (porém) é mais curto." - Just to avoid alliteration.

Mr-Saxobeat · 2019-10-23T21:17:18Z

1-js/02-first-steps/07-operators/article.md


 *!*
-// both values converted to numbers before the binary plus
+// ambos valores convertidos para números antes do mais binário


"... binário mais"

+Normalmente, o operador mais `+` soma números.

-But, if the binary `+` is applied to strings, it merges (concatenates) them:
+Mas, se o binário `+` é aplicado em strings, junta (concatena) elas:

"...é aplicado em a strings, ele junta (concatena) elas:"
