 # Recognizing the Symbols of Roman Numbers in Mathematics Math formulaIn elementary mathematics lessons, you will definitely learn about how to write numbers using Roman symbols or numbers. By replying to this material greeting I will invite you to recognize roman numerals in mathematics. In this article, we will explain in detail about the basic symbols of Roman numbers and how to write them. In general, the basic symbols of Roman numerals consist of 7 pieces, namely: ## Roman Numbers and How to Write

There are many ways that we can do to write a roman number. The first method is known as the repetition system.

### Repeat System

In the loop system we can only repeat the symbol no more than 3 times. Symbols of roman numbers that can be used and written with the repetition system are I, X, C, and M. While the symbols for roman numbers that are not written with the repetition system are V, L, and D. Consider the example of writing roman numbers with the repetition system below. :

I = 1
II = 2
III = 3

X = 10
XX = 20
XXX = 30

C = 100
CC = 200
CCC = 300

M = 1000
MM = 2000
MMM = 3000

How? I understand? If you already understand, let’s continue with the next way of writing roman numbers.

### Subtraction system

The second way we can write a roman number is with the subtraction system. In the subtraction system, the number on the right can be subtracted from the number on the left if the number on the left is less than the number on the right. the deduction system only applies once. The following is an example of writing Roman numbers using the subtraction system:

IV = 5 – 1 = 4
IX = 10 – 1 = 9
XL = 50 – 10 = 40
XC = 100 – 10 = 90
CD = 500 – 100 = 400
CM = 1000 – 100= 900

### Sum system

The next way to write Roman numbers is with the addition system. The addition system can only be done if the number is followed by a number whose value is the same or less. The addition system can only be done a maximum of 3 times. Consider the example of writing roman numbers with the addition system below:

VI = 5 + 1 = 6
VII = 5 + 1 + 1 = 7
XI = 10 + 1 = 11
XII = 10 + 1 + 1 = 12
LX = 50 + 10 = 60
XVI = 10 + 6 = 16
CL = 10 + 50 = 60
DC = 500 + 100 = 600
MD = 1000 + 500 = 1500

Addition of 3 numbers:

VIII = 5 + 1 + 1 + 1 = 8
XIII = 10 + 1 + 1 + 1 = 13

### Combined System

The way to write roman numbers is to use a mixed system of domanas in writing combining addition and subtraction of roman numbers as shown in the example below:

CXLIX = 100 + (50-10) + (10-1) = 149
XXIV = 10 + 10 + (5-1) = 24
CMXCVIII = (1000 – 100) + (100-10) + 8 = 998

### How to write roman numbers from 1 to 1 billion Table description:
Sign 1 strip above the roman number means the number is multiplied by 1000
Sign 2 strips above the roman number means the number is multiplied by 1000.000

A few discussions of discourse material recognize roman numerals in mathematics. Hopefully after reading the discussion of the material above you can memorize and be able to write down the numbers using the Roman numeral symbol correctly. ## 1080P Full HD by IMX291 Low Illumination 0.001Lux Starlight CCTV USB Camera PCB Board 2MP USB2.0 Camera Module MJPEG YUY2 ## Your Xiaomi Redmi 2 goes into Deep Sleep Mode so that when you want to turn on the screen, you have to press the long power button?
