An online binary calculator allows you to do addition, subtraction, multiplication, or division on two binary numbers as well as with 8, 10 & 16 base numbers. Now, it becomes handy to get an exact binary (bit) figure, the online binary operations calculator supports common mathematical operations over binary numbers.

Well, keep eye contact with this context to find how to add, subtract, multiply, and divide numbers step-by-step.

Binary Overview:

According to mathematics and digital electronics, a binary number is referred to as a number that expressed in the base-2 numeral system or binary numeral system. The binary number uses only two symbols that includes: “0” (zero) and “1” (one). Remember that the base-2 numeral system is said to be as a positional notation with a radix of 2. Also, each digit is referred to as a bit, or known as binary digit.

Well, simply enter any numbers into this binary calculator and lets it will perform calculations with mathematical operation.


When you say a binary numeral number, you need to pronounce each digit, (for example: the binary number “101” is simply spoken as “one zero one”, or sometimes said as “one-oh-one”). Once you exactly know about the binary term, you don’t get confused with the decimal number. A single binary digit (like “0” or “1”) is known as a “bit”. For example 111010 is six bits long.

Decimal Binary
0 0
1 1
2 10
3 11
4 100
7 111
8 1000
10 1010
16 10000
20 10100

Now, you can easily convert decimal numbers to fractions by using an online decimal to fraction calculator by calculator-online. Also, you can try fraction to decimal calculator that used to reduce fractions and mixed numbers into the simplest form.

How to Add, Subtract, Multiply & Divide Binary Numbers?

The online binary calculator performs the following arithmetic calculations on the two numbers with the same bases.

  • Addition
  • Subtraction
  • Multiplication
  • Division

Here, we have examples of operations on the binary numbers. Same as it is for the calculations of the hexadecimal, octal & decimal numbers.

Binary Addition:

Adding binary numbers follows the same rule as in the decimal addition, but it carries 1 rather than 10. Our binary addition calculator performs the adding rules for the addition of binary numbers. Look at the given table for a better understanding of the logic of adding binary numbers.

A +B Sum Carry
0 + 0 0 0
0 + 1 1 0
1 + 0 1 0
1 + 1 0 1

Also, if you want to perform long addition for different numbers, then the online long addition calculator works best for you!


Add (10110010)2 & (11101)2?




+    (11101)2




Binary Subtraction:

Subtracting binary numbers follows the same rule as in the decimal subtraction, but it borrows 1 rather than 10. Use binary subtraction calculator to exactly know about the rules for the binary subtraction. Ahead to the example for better understanding.


How to subtract binary numbers (11101)2 from (100011)2?



\(0 – 0 = 0\)

\(0 – 1 = 1 borrow 1\)

\(1 – 0 = 1\)

\(1 – 1 = 0\)



–     (11101)2



Binary Multiplication:

It is simpler than decimal multiplication as it consists of only 0 & 1. Our binary multiplication calculator readily performs the multiplication of binary numbers. Ahead to example:


Multiply (101011)2 with (101)2?


\(0 × 0 = 0\)

\(0 × 1 = 0\)

\(1 × 0 = 0\)

\(1 × 1 = 1\)



×       (101)2







Binary Division:

It is similar to the long division of decimal numbers. In our binary division calculator, the dividend is divided by the divisor same as in the decimal. Let’s have a look at the example:


Divide (101010)2 with (110)2?



110 ⟌101010



















Simply, you can try this binary number calculator to verify your answers and to avoid from complications.

Frequently Ask Questions (FAQ’s):

Is 99 binary or decimal?

99 is a decimal number as the numbers in the 99 included in the decimal digits (0,1,2,3,4,5,6,7,8,9) & binary numbers consists of only 0 & 1.

What is a binary number?

The numbers with the base 2 rather than 10 is in the binary system. It is expressed only with 0

& 1.

Why we do need binary number?

It is basically used in discrete mathematics to represent the logic gates. It is the basic of the electronic devices because it is the part of Boolean algebra.


The binary numbers are important in our daily life instead of using decimal we can use binary as it simplifies the design of computer & related technologies. So, thankfully, you come to know about binary calculations that might be helpful in different systems. Simply, try this online binary calculator that helps you to do the arithmetic calculations accurately.
