+# The Translator
+
+> **[INCOMING — Mission Control, Earth]**
+>
+> Cadet, when input comes in as text (a `str`), you can't do math
+> with it directly. You have to *translate* it to a number.
+>
+> Three converters:
+>
+> - `int("42")` → `42`
+> - `float("3.14")` → `3.14`
+> - `str(42)` → `"42"`
+>
+> Implement `years_until(age)` that returns `100 - age` as an `int`.
+> The argument may arrive as either `int` or `str` — handle both
+> by calling `int()` on it first.
+>
+> [END TRANSMISSION]
+
+## Your Task
+
+Open `starter/starter.py`. Convert `age` with `int()`, then return
+`100 - age`.
+
+## Objectives
+
+- `years_until(25)` returns `75`
+- `years_until("25")` also returns `75` (handles string input)
+- Works for any integer age 0–100
