55 · Decimal tallies

Read right to left: 20 + 20 + 10 + 3 + 2.

Worked example

Write 55 in Phoenician

Start at the right and move left, writing the larger values first in reading order. Add the values of the signs.

  1. Write 2 signs worth 20 each: 2 × 20 = 40.

  2. Write this sign for 10. Its value is 10 by itself.

  3. Write this sign for 3. Its value is 3 by itself.

  4. Write this sign for 2. Its value is 2 by itself.

Check

2 × 20 + 10 + 3 + 2 = 55

Meet the symbols

Each tile shows a sign and what it means. A sign can stand for a whole amount, such as 10 or 100.

How the symbols fit together

Begin at the right-hand end and add the sign values as you move left.

  1. For 55, start with two twenty signs: 20 + 20 = 40.
  2. Continue to the ten sign. The running total becomes 40 + 10 = 50.
  3. The remaining three and two signs add five: 50 + 3 + 2 = 55.
  4. For 42, use two twenties and a two: 20 + 20 + 2. The converter groups unit tallies into the fewest available signs.

3 in Phoenician

The three-tally group.

42 in Phoenician

Read right to left: 20 + 20 + 2.

55 in Phoenician

Read right to left: 20 + 20 + 10 + 3 + 2.

The app supports the straightforward additive range 1–99. Larger inscriptions can involve additional conventions, so the hundred sign is documented without extrapolating a general hundreds algorithm. There is no zero digit.

History

Phoenician writing spread across Mediterranean networks and continued in Punic forms. Its numerical notation uses repeated signs, with dedicated marks for ten, twenty, and hundred alongside small tally groups.

How to read it

Begin at the right-hand end and add the sign values as you move left.

  1. For 55, start with two twenty signs: 20 + 20 = 40.
  2. Continue to the ten sign. The running total becomes 40 + 10 = 50.
  3. The remaining three and two signs add five: 50 + 3 + 2 = 55.
  4. For 42, use two twenties and a two: 20 + 20 + 2. The converter groups unit tallies into the fewest available signs.

Limits

The app supports the straightforward additive range 1–99. Larger inscriptions can involve additional conventions, so the hundred sign is documented without extrapolating a general hundreds algorithm. There is no zero digit.
