## Exemples

**1.** Solve a chain of complex operations.

```TypeScript
import TheMath from 'the-math';

const chain = TheMath.createChain({
  round: {
    type: 'floor',
    precision: 2
  }
});
const result = chain(4.91231).plus(2.12413).done();
// result: 7.03
```

**2.** Solve subtraction between 2 numbers.

```TypeScript
import TheMath from 'the-math';

const result = TheMath.subtract(10, 3);
// result: 7
```

**3.** Solve sum between 2 numbers.

```TypeScript
import TheMath from 'the-math';

const result = TheMath.sum(14, 7);
// result: 21
```

**4.** Solve division between 2 numbers.

```TypeScript
import TheMath from 'the-math';

const result = TheMath.divide(21, 3);
// result: 7
```

**5.** Solve multiplication between 2 numbers.

```TypeScript
import TheMath from 'the-math';

const result = TheMath.multiply(6, 3);
// result: 18
```

**6.** Solve a string operation arithmetic.

```TypeScript
import TheMath from 'the-math';

const result = TheMath.resolve('12+4*3*9/2+1');
// result: 67
```
