Detailed explanation-1: -The Phoenician numeral system consisted of separate symbols for 1, 5, 10, 20, and 100. The sign for 1 was a simple vertical stroke. Other numbers up to 9 were formed by adding the appropriate number of such strokes, arranged in groups of three. The symbol for 10 was a horizontal line or tack.

Detailed explanation-2: -The Phoenicians represented the numbers 1–9 by the respective number of vertical strokes. Ten was usually designated by a horizontal bar. The numbers 11–19 were expressed by the juxtaposition of a horizontal stroke and the required number of vertical ones. A table should appear at this position in the text.
