+
+Create an object `calculator` with three methods:
+
+- `read()` prompts for two values and saves them as object properties.
+- `sum()` returns the sum of saved values.
+- `mul()` multiplies saved values and returns the result.
+
+```js
+let calculator = {
+  // ... your code ...
+};
+
+calculator.read();
+alert( calculator.sum() );
+alert( calculator.mul() );
+```
