- Define and explain roman seven symbols.
- Apply roman seven symbols to a focused FBISE question.
- Check the answer for correct terms, evidence, working, and units.
Definition
Roman numerals use seven symbols I, V, X, L, C, D, M for 1, 5, 10, 50, 100, 500, 1000. There is no zero, so they cannot mark an empty place. Adding IX and XI by hand is clumsy compared with 9 + 11. The system is fine for dates on a clock, but it is a poor tool for school algebra.
