Drag to sort

Identify which numbers are Rational (terminating/repeating) and Irrational (non-repeating, endless).

Rational

Irrational

Tap to select

The sum of a Rational and an Irrational is ALWAYS Irrational.
Tap all the expressions that result in an Irrational number.

Great job! Rational + Irrational = Irrational!

Slide to multiply

Multiplying by an irrational usually keeps it irrational.
Find the ONLY rational multiplier that destroys the irrational part!

{{ step3.multiplier }} × = {{ (step3.multiplier * 1.41421356).toFixed(4) }}... 0
Result is {{ step3.multiplier === 0 ? 'RATIONAL' : 'IRRATIONAL' }}

Master of Irrationals!

You've sorted the endless decimals, discovered that mixing them keeps them wild, and found the only zero-point loophole!
