Roman Counting 1 to 100

Adding Up the Roman Numerals: If you put symbols together, you add them up. Like II is 1 + 1 = 2 and XX is 10 + 10 = 20.

Special Trick – Subtracting for Roman Numbers: Sometimes, we do a little trick. If a smaller number comes before a bigger one, it means “take me away!” So, IV is like saying 5 – 1 = 4.

Building Roman Numbers: You can build bigger numbers by adding symbols. After a bigger symbol, if you put a smaller one, add them up. Like VI is 5 + 1 = 6.

No Repeats for Some: The symbols V, L, and D are loners; they don’t like to repeat. So, you won’t see VV for 10, it’s always X.

Keep It Ordered: Usually, we start with the biggest symbols and go down to the little ones. Like CXXIII for 123.

Zero? What’s That?: Romans didn’t use a symbol for zero. They probably just said “nothing”!

Three’s a Crowd: You can repeat symbols like I, X, C, and M up to three times. But no more than that!

Subtracting Rules: You can only subtract a bit at a time, and only from certain symbols. Like I can sneak in front of V or X, but not before L.
