31. Math

The code outputs the following:

```
Infinity
NaN
-Infinity
NaN
Infinity
-Infinity
NaN
NaN
Infinity
NaN
NaN
NaN
```

Explanation:

`console.log(1 / 0)`

outputs`Infinity`

because any positive number divided by zero is infinity.`console.log(0 / 0)`

outputs`NaN`

(Not a Number) because it is an undefined and indeterminate operation.`console.log(-1 / 0)`

outputs`-Infinity`

because any negative number divided by zero is negative infinity.`console.log(1 / 0 * 0)`

outputs`NaN`

because`1/0`

is infinity and any number multiplied by infinity is undefined.`console.log(1 / 0 * 1)`

outputs`Infinity`

because`1/0`

is infinity and any number multiplied by infinity is infinity.`console.log(1 / 0 * -1)`

outputs`-Infinity`

because`1/0`

is infinity and any number multiplied by negative infinity is negative infinity.`console.log(1 / 0 * 1 + 1 / 0 * 1)`

outputs`NaN`

because both operations result in infinity and infinity plus infinity is undefined.`console.log(1 / 0 * 1 - 1 / 0 * 1)`

outputs`NaN`

because both operations result in infinity and infinity minus infinity is undefined.`console.log(1 / 0 * 1 * (1 / 0 * 1))`

outputs`Infinity`

because`1/0`

is infinity and any number multiplied by infinity is infinity.`console.log(1 / 0 * 1 / (1 / 0 * 1))`

outputs`NaN`

because both division operations result in infinity and infinity divided by infinity is undefined.`console.log(0 / Infinity)`

outputs`0`

because any number divided by infinity is zero.`console.log(0 * Infinity)`

outputs`NaN`

because any number multiplied by infinity is undefined.
