>     "difference": a - b,

> Convert both inputs with `float()` so results are consistent — and

## Your Task

In `starter/starter.py`, convert both inputs to float, then return
the dictionary with the four keys above.

## Objectives

- `calculate(10, 5)` returns the four operations as a dict
- Works with int, float, and string inputs
- All values are floats
