### A good answer might be:

```Math.sin( 0.5 ) >= Math.tan( 0.2 ) || 43.259 / 12.073 > 3.5 || ( 100 > 45 )
```

There are no side-effects here, so it is safe to look at the last part:

```( 100 > 45 )
```

and realize that the entire expression will be `true`. Java (working from left to right) might have found a different `true`, but in the absence of side-effects that doesn't matter. The entire expression is `true`.

Math functions, such as `Math.sin()` and `Math.cos()`, do not have side effects. They are safe to use in boolean expressions.

# Red Miata Sports Car

Say that you have not yet given up on buying that \$25,000 red Miata sports car. The sales manager of the car lot will let you buy the car if:

• You have at least \$25,000 in cash, OR
• You have at least \$25,000 in credit AND no outstanding debts.

The logic of this situation is slightly complicated. Here are several situations:

• You have \$30,000 in cash, no credit and massive debts.     You get the car.
• You have \$1,000 in cash, \$50,000 in credit and massive debts.     You DON'T get the car.
• You have \$1,000 in cash, \$10,000 in credit and no debts.     You DON'T get the car.
• You have \$1,000 in cash, \$30,000 in credit and no debts.     You get the car.

Notice that it is not enough to merely have a high credit line. To buy the car on credit you must also be free of debt.

### QUESTION 12:

You have \$25,000 in cash, \$50,000 in credit and massive debts. Do you get the car?
