The number 4 in Roman Numeral stands for IV. I stand for 1 and V stands for 5. When you put I before V it means you subtract 1 from 5 which gives 4. So, IV is how the Romans represented four. You may have seen that roman numerals were used in architecture.
In IV , I stand for 1 and V stands for 5. When you put I before V, it means you subtract 1 from 5, which equals 4. So, IV stands for 4 in Roman Numerals.
Rule 1: Addition Rule
Addition of two numerals i.e., greater and smaller numeral. For example, I (1) plus II (2) makes III (3).
Ⅰ + Ⅱ = Ⅲ or 1 + 2 = 3
Rule 2: Repetition Rule
Repetition of numerals cannot be done more than thrice, and then the number is added. This is known as the repetition method. For example, II is 2, and III is 3, but you can't do this for 5.
Ⅱ is 2 correct
Ⅲ is 3 correct
ⅡⅢ is not 5 wrong
Rule 3: Subtraction Rule
Subtraction of the smaller number from the larger number, and the larger numeral is written after the smaller numeral.
Ⅴ - Ⅰ = Ⅳ or 5 - 1 = 4
Rule 4: Limitation Rule
We add or subtract numbers to obtain the desired numbers, as the same symbol cannot be repeated more than 3 times. For example, you can't write IIII for 4; instead, use IV.
Ⅲ correct
ⅡⅡ wrong
Ⅳ correct
In roman numerals, we write 4 as IV.to get the desired number, we use subtraction and addition rule and combine them. We write roman numerals in methods explained below:
This method includes breaking down numbers based on their place values like thousands, a hundred, tens, and ones respectively. Every place value is written in the form of roman numerals.
This method works as shown below:
This method involves breakdown of large numerals into small parts based on their Roman numeral values. This method works as follows:
Add IV+VI.
Subtract IX-IV.
Solve IV+VII-III.
Solve X-IV+II
