Always finds the “why”
PIA Explorer
Explores the idea before the method.
Starts with why a rule exists, then shows you how to use it. Good if a formula feels arbitrary until you know where it came from.

A neutral presentation of the maths, without a personality-specific style. Tutor access follows your study assignment; previewing this style does not select it.

How a lesson works
Big problem?
Cut it into panels.
Percentage problems can be broken into smaller steps. A ₱100 bag now costs ₱120. What is the percentage increase? This example shows the calculation.
-
The problem
₱100 to ₱120
PIA: The price went up. By what percent? Let’s find out.
-
Find the change
₱120 − ₱100 ₱20 more
PIA: First, how much did it go up? New price minus old price.
-
Compare to the start
20 ÷ 100 = 0.20
PIA: Divide by the ORIGINAL price, where it started. That’s the whole trick.
-
Done
20%
Check: 20% of ₱100 = ₱20 ✓
Self-determination theory
Support for your learning
PIA’s design draws on autonomy, competence and relatedness from self-determination theory: opportunities to act, practise and receive support.
-
Take an active role
Ask for a hint when you need one. Some study groups choose a tutor; others receive an assignment.
Autonomy: choices follow the study rules for your account.
-
Practise step by step
Work on finding percentages, percentage increases and percentage decreases, with feedback on your answers.
Competence: practise with hints and answer feedback.
-
Learn with guidance
Explore different ways of presenting guidance while you practise. Your tutor is part of the learning application.
Relatedness: a consistent tutor presence during your activities.
