The process is the same across the abacus to indicate a digit for each place value. Push up additional beads from the bottom row to continue the count. Together the top row (a value of 5) and the bottom row (a value of 1), this represents a total value of 6. To count to "six," push one bead from the bottom row up. To indicate the number “five”, push the bead from the top row to the "down" position (a value of 5), and push all four beads from the bottom row down (a value of 0), for a total value of 5.
The top row bead represents a value of 5. Push up two beads for "two", etc.Ī pro tip for speedy arithmetic: use your thumb to manipulate beads in the bottom row and your index finger for beads in the top. The number "one" would be represented by pushing up a single bead from the bottom row, where each bead represents a value of 1. Likewise, to represent a number like 12.55, the furthest right column would be the “hundredths” place, to its left would be the “tenths” place, followed by the “ones” place, and then the “tens” place. For example, if you are representing a number like 12.5, then the furthest right column would be the “tenths” place (the first decimal place), to its left would be the “ones” place, followed by the “tens” place. You can also assign columns to be decimal places. Starting from the right are the "ones" place, to its left is the "tens" place, followed by the “hundreds”, “thousands” and so on. Assign each column a place valueĮach column of beads represents a place value.
Each bead in the top row represents a value of 5 and each bead in the bottom row represents a value of 1. This is the default position for each column. All of the top row beads should be in the up position, and down in the bottom row. Position your abacus and default your beadsĮach column has one bead in the top row, and four beads in the bottom.
