Operator

Operator is a daily math puzzle where your mission is to arrange numbers and operators to hit an exact target value.

You start with a goal number and a set of digits. Build an equation using addition, subtraction, multiplication, or division. Find one correct equation to win, then keep finding solutions to fill the progress bar.

• Tap digits and operators to build your equation, then press Submit.
• Calculations run left to right.
• You don't need to use every space. Two numbers and one operator can be enough.
• Each digit can appear only once per equation.
• Every intermediate result must stay a positive whole number, so division must come out evenly.
• Use Shuffle to rearrange the digits on the dial for a fresh perspective.
• Hint reveals the shape of one solution if you need a nudge.
• A new puzzle drops every day.

Why we like it:

• ✅Scratches the same itch as Countdown or mental math warm-ups, with a clean, modern interface.
• ✅Find one solution for a quick win, or keep going for a longer challenge.
• ✅Simple arithmetic leaves plenty of room for clever combinations.

Hint: Try working backward from the target. If your goal is 16 and you have a 5 available, finishing with “− 5” means you need to make 21 first. Can you get there with the other digits?
