Distance from Zero
The absolute value is just a number's distance from zero. It's always positive!
Find
{{ i-11 }}
🚀
Correct! Distance is {{ Math.abs(s1.target) }}.
Distance: {{ Math.abs(s1.pos) }} steps
Tap to pop
Find the Matches
Pop all bubbles that have an absolute value of {{ s2.target }}.
{{ opt.val }}
✨
Great! Both {{ s2.target }} and -{{ s2.target }} have a distance of {{ s2.target }} from zero.
Tap to compare
Which is bigger?
Evaluate the absolute values first, then tap the center circle to choose the correct sign.
= {{ Math.abs(s3.left) }}
= {{ Math.abs(s3.right) }}
Perfect! {{ Math.abs(s3.left) }} {{ ['?','<','=','>'][s3.opIdx] }} {{ Math.abs(s3.right) }}
Drag to sort
Order by Size
Sort these expressions from least to greatest absolute value.
All sorted!
{{ idx === 0 ? 'Least' : (idx === 3 ? 'Greatest' : '') }}
= {{ slot.abs }}
Brilliant sorting!
