## What is Infinity Math?

Infinity Mental Math is a brain-training game of arithmetic — addition, subtraction, multiplication and division — that you can enjoy endlessly. See how many problems you can breeze through before your time runs out.

■ Play forever
Every problem is generated fresh, so there is always a new one waiting. Solve as many as you like; the next one is already on its way. Nothing is pre-made.

■ Simple controls
Just enter the answer on the number pad. When you reach the right number of digits, it moves to the next problem automatically — no confirm button. Large, high-contrast text keeps everything easy to read.

How to play
Just enter the answer on the number pad. A correct answer adds time and moves you to the next problem. Early problems are easy so you can find your rhythm, then they grow harder to match your skill. When the time runs out, the run ends — and your best streak is saved.

Great for anyone who loves numbers or mental math, and for a daily mental workout — at any age.
