Arithmetic for Computer: Binary Operation (EASY)

Have you done knowing how to make a number conversion on the entry published before? Now, we move to the next step in arithmetic for computer. It is about binary operation. Binary operation only use:

  • addition
  • substraction
  • multiplication
  • division

Quite easy right? No? Relax, do not get tempered and flip your table :D Let us continue..

Adding, subtracting, multiplying and dividing binary numbers is a very simple task, and very similar to the longhand addition of decimal numbers. As with decimal numbers, you start by adding the bits (digits) one column, or place weight, at a time, from right to left. Unlike decimal addition, there is little to memorize in the way of rules for the addition of binary bits:

0 + 0 = 0
1 + 0 = 1
0 + 1 = 1
1 + 1 = 10
1 + 1 + 1 = 11
and so on.

*(This rules, you must memorize it clearly. So that, you will easily get the concept and idea of binary operation.)

Just as with decimal addition, when the sum in one column is a two-bit (two-digit) number, the least significant figure is written as part of the total sum and the most significant figure is "carried" to the next left column. Consider the following examples:

.                          11  1 <--- Carry bits ----->  11
.     1001101             1001001                     1000111
.   +0010010          + 0011001                 + 0010110
.   ---------                 ---------                   ---------
.     1011111             1100010                     1011101

That is all for addition for binary numbers. Easy? Or still get confused? How about subtraction? Multiplication? Division? Do not worry, I have prepared a video that will tell you all about binary operation below.

Actually, there is no difference of basic mathematics that we learnt before with binary operation. Why? Let me show you one of the video that will made you clear about this.

I am sure after you watch this video, you will find out that binary operation is easy as abc. Enjoy!

That is all for this subtopic. Make sure that you follow all of our entries in this blog later. Do not forget to leave your comment. Good luck!
