Welcome to the Digital Abacus Manipulative! This mathematical learning tool translates abstract arithmetic values into spatial logic patterns.
- Moving Beads: Click or Tap directly on any bead to slide it. Tapping a bead moves it along with all consecutive adjacent values.
- Counting Rules: Inactive beads rest at the top. Slide beads down to activate them.
- Place Values: Columns display numbers from right to left (Ones, Tens, Hundreds, Thousands... up to Hundred Crores / Billions).
- Keyboard Accessibility: Press
Tab to focus onto a rod wire. Use Up Arrow and Down Arrow to adjust values dynamically. Navigate across wires using your Left Arrow and Right Arrow keys.
