Arithmetical Operations

Addition (addends, sum).

Addition – an operation of finding a sum of some numbers: 11 + 6 = 17. Here 11 and 6 – addends, 17 – the sum. If addends are changed by places, a sum is saved the same: 11 + 6 = 17 and 6 + 11 = 17.

Subtraction (minuend, subtrahend, difference).

Subtraction – an operation of finding an addend by a sum and another addend: 17 – 6 = 11. Here 17 is a minuend, 6 – a subtrahend, 11 – the difference.

Division(dividend, divisor, quotient, dividing integers, fraction, divisible numbers, remainder, division without remainder, division with remainder).

Division – an operation of finding one of factors by a product and another factor: 48 : 4 = 12. Here 48 is a dividend, 4 – a divisor, 12 – the quotient. At dividing integers a quotient can be not a whole number. Then this quotient can be present as a fraction. If a quotient is a whole number, then it is called that numbers are divisible, i.e. one number is divided without remainder by another. Otherwise, we have a division with remainder. For example, 23 isn’t divided by 4 ; this case can be written as: 23 = 5 · 4 + 3. Here 3 is a remainder.

Raising to a power (power, base of a power, index or exponent of a power, value of a power).

Raising to a power. To raise a number to a whole (second, third, forth, fifth etc.) power means to repeat it as a factor two, three, four, five and so on. The number, repeated as a factor, is called a base of a power; the quantity of factors is called an index or an exponent of a power; the result is called a value of a power. A raising to a power is written as:

3 5 = 3 · 3 · 3 · 3 · 3 = 243 .

Here 3 – a base of the power, 5 – an exponent (an index) of the power, 243 – a value of the power.

The second power is called a square, the third one – a cube. The first power of any number is that number.

Extraction of a root (root, radicand, index or degree of aroot, value of a root, square root, cube root).

Extraction of a root – an operation of finding a base of a power by the power and its exponent:

Here 243 – a radicand, 5 – an index (degree) of the root, 3 – a value of the root. The second root is called a square root, the third root – a cube root.

Greatest common factor (GCF). Finding GCF.

Common factor of some numbers – a number, which is a factor of each of them. For example, numbers 36, 60, 42 have common factors 2, 3 and 6 . Among all common factors there is always the greatest one, in our case this is 6. This number is called a greatest common factor (GCF).


Least common multiple (LCM). Finding LCM.

Common multiple of some numbers is called a number, which is divisible by each of them. For example, numbers 9, 18 and 45 have as a common multiple 180. But 90 and 360 are also theirs common multiples. Among all common multiples there is always the least one, in our case this is 90. This number is called a least common multiple (LCM).

Merubah IP Address dalam desimal menjadi angka biner

Rekan-rekan Numpang Share

Pada artikel sebelumnya saya telah menjelaskan bagaimana merubah bilangan biner (binary) kedalam bilangan decimal dengan contoh kasus alamat IP Address di jaringan komputer.

Pada kesempatan kali ini, saya akan melanjutkan kembali pembahasan kita tentang bilangan biner dan decimal, tapi dengan materi yang sedikit berbeda yaitu bagaimana merubah bilangan decimal pada contoh kemarin kembali menjadi bilangan biner (binary). Okey…..Selamat belajar :)

Contoh :

Rubah kembali alamat IP Address menjadi bilangan biner ?


IP Address merupakan alamat IPv4 yang terdiri dari 4 bagian dan jika dalam bentuk binernya setiap bagian terdiri dari 8 bit.

Bagian I : 192

Untuk merubah bilangan decimal menjadi bilangan biner maka bilangan tersebut harus dibagi dengan 2 berkali-kali sehingga nilainya menjadi 1

Sehingga 192 jika dirubah ke bentuk biner menjadi : 11000000

Bagian 2: 168

Sehingga 168  jika dirubah ke bentuk biner menjadi : 10101000

Bagian 3: 100

Sehingga 100  jika dirubah ke bentuk biner menjadi : 1100100. (7 bit)
Hmm…coba rekan-rekan perhatikan jumlah bilangan binernya hanya ada 7 bit, sementara setiap bagian pada IPv4 harus terdiri dari 8 bit bilangan biner. Jika terjadi hal di atas, solusinya adalah  tambahkan nol (0) sebanyak digit yang kurang sehingga menjadi 8 bit.
Sehingga bilangan biner untuk 100 adalah 01100100

Bagian 4 : 103

Sehingga 103  jika dirubah ke bentuk biner menjadi : 1100111. (7 bit)
Karena ada 7 bit, tambahkan nol  ( 0) sehingga bilangan biner untuk 103 menjadi 01100111
Jadi, bilangan biner untuk IP Address adalah :

11000000. 10101000. 01100100. 01100111

Mudah bukan, selamat mencoba pada IP Address yang lain dan semoga bermanfaat :)

Bagaimana Mengkonversikan Bilangan biner (binary) menjadi Bilangan Desimal???

Ini sebenarnya merupakan materi kuliah yang saya berikan kepada mahasiswa  di AMIKI pada mata kuliah Jaringan Dasar. Tapi rasanya tidak salah jika saya share disini, mungkin saja ada rekan-rekan Numpang Share yang membutuhkannya…so..selamat membaca :)

Rekan-rekan Numpang Share sekalian

Konversi Biner ke Desimal biasanya digunakan untuk merubah format penulisan IP Address yang awalnya ditulis dalam angka biner  (0 dan 1) lalu dirubah ke dalam angka desimal dengan tujuan agar gampang untuk diingat. Hmmmm bingung…..okey akan saya kasi gambarannya, sekarang coba  anda bandingkan format penulisan IP Address dibawah ini

IP Address ditulis dalam bentuk bil. biner :


IP Address yang sama tapi ditulis dalam bentuk bil. desimal :

Yang mana yang lebih mudah buat di ingat????  u Choice :)

Baik, sekarang saya akan menjelaskan gmn cara buat konversi IP Address diatas. Perhatikan contoh soal dibawah ini:


Rubahlah IP address berikut ke dalam bentuk bilangan decimal



Jika kita perhatikan alamat IP address diatas maka dapat disimpulkan bahwa itu adalah alamat IP versi 4 (IPv4). Alamat IPv4 adalah bilangan biner 32 bit yang terbagi menjadi empat kelompok, sehingga masing-masing kelompok terdiri dari bilangan biner 8 bit.

Jadi untuk merubah bilangan biner diatas, alangkah mudahnya jika kita rubah satu persatu.

Bagian I : 11000000

  1. Masukkan bilangan biner diatas kedalam tabel berikut:
  2. Kalikan setiap bilangan biner diatas dengan bilangan 2 berpangkat* sehingga diperoleh hasil perkaliannya.
  3. Tambahkan hasil perkalian diatas “128+64+0+0+0+0+0+0 = 192”. Nilai 192 merupakan hasil konversi bilangan biner pada Bagian I

Bagian II: 10101000

Hasilnya : 128+0+32+0+8+0+0+0 = 168

Bagian III : 01100100

Hasilnya : 0+64+32+0+0+4+0+0 = 100

Bagian IV : 01100111

Hasilnya : 0+64+32+0+0+4+2+1 = 103

Jadi alamat IP 11000000.10101000.01100100.01100111 jika dirubah kedalam bentuk bilangan decimal ditulis :

Hmmmm…mudahkan…semoga bermanfaat :)


*)Bilangan biner atau bilangan basis dua adalah sebuah sistem penulisan angka dengan menggunakan dua simbol yaitu 0 dan 1
