Trio Math
Train your Brain!
Free · In‑App Purchases · Designed for iPad
Sharpen your mental math skills with Trio.
Find hidden Trios in the number grid by selecting three numbers in a row and calculating their result to match the target number. Each valid Trio must include one multiplication and one addition or subtraction - no simple sums allowed. Multiple solutions exist for each target number, so think strategically and act fast to earn three stars.
How to play:
Find three numbers that form the target number
Use one multiplication and one addition or subtraction
Think creatively - brackets are allowed
For example, to reach 9, you could choose:
3 × 5 - 6 = 9
5 + 2 × 2 = 9
(6 - 3) × 3 = 9
But using two additions is not allowed:
5 + 2 + 2 = 9 (No multiplication used)
Features:
