How Do You Calculate Binary Numbers?

If you’re curious about how to calculate binary numbers, a good place to begin would be with basic number theory. Binary numbers contain only either 1 or 0.

To convert decimal numbers to binary numbers, start by ignoring their decimal sign and dividing by 2, keeping an eye on both its integer quotient and remainder values.

Binary numbers consist of eight characters long and are made up of either one 1 or zeroes, where each position corresponds to a different numerical value. To calculate one, first determine its place value before adding or subtracting values for adjacent positions. To simplify calculations further, any number if divided by zero gives an integer quotient equalling zero, which you can multiply with your base to get its decimal equivalent; this makes calculation quicker.

If you are familiar with decimal math, transitioning to binary should be straightforward. Decimal employs base 10, while binary uses base two; simply divide any number by two to convert to binary and get its equivalent in decimal. This will provide the basis of further expansion within your number system.

Calculating binary numbers requires starting with the first digit and working your way leftward. Each digit has a specific value; if not zero-based, its power is two to its location (one). Continue this pattern for each of the other digits until all ones have been added together.

As binary is a two-digit number system, its most significant digit always remains 1. This makes signing binary operations simple to perform such as addition and subtraction; additionally complementation allows representation of negative binary numbers.

Once you’re finished adding up your ones, subtract them back out until you are left with just the value of the original number. From there, write it in its appropriate column; for instance, to find the binary equivalent of 86 you would write it in the sixty-fours column (binary numbers are written from right to left).

Convert any binary number to decimal by following the same process, but now working in base 10 instead. While this approach requires more work because each digit’s sign must be determined before adding them together, it provides an excellent way of becoming acquainted with binary number systems before moving onto more advanced methods.


There are three basic types of binary numbers – bits, bytes and words. A bit is defined as one binary digit while each byte and word contain eight binary digits each. When used in computer circuitry to add, subtract or multiply values, binary numbers play an integral part. To calculate them yourself start at the most significant digit and work your way outward – each digit corresponds with its own power of two; so for instance if one of your first digits was 1 then multiply two by itself before moving onto the next digit and so forth until reaching all 16 leftmost digit.

At its core, binary numbers are all multiples of two. When working with them, remember this fact – each digit should be doubled before adding it back together again before moving onto the next digit in your binary number. You will repeat this process for each of its digits until you reach a final result which can then be written down – something we do repeatedly for every number in binary form.

Binary multiplication is similar to decimal multiplication, but has some distinct differences. When multiplying binary numbers, each digit of the multiplier must be multiplied with every digit of its respective multiplicand before adding all partial products for a final total result.

When working with binary numbers, it is essential to keep in mind that any number can either be positive or negative. To create a negative binary number, change the most significant bit to 1; conversely, to create a positive binary number change the least significant bit to 0.

Binary subtraction is straightforward and can be accomplished by dividing any binary number by 2. Once you have taken the remainder from this quotient, identify any powers of two that are smaller than it. When you find one that matches, write one beside it and subtract that value from your binary number – repeat this process until all powers of two have been added together.


A remainder is the part of a number that cannot be divided by another number, for instance when you divide 69 by 6, the quotient will be 6; however, 7 is not divisible by 6 leaving an outstanding remainder of 3. Mathematics offers various methods to calculate remainders; one such way is long division.

This method uses the dividend as the large number you wish to divide, and divisor as the smaller number which divides that dividend into multiples. The quotient represents the final result of this division process and remainder represents any amount remaining afterward.

Short division is another effective and simple method for finding remainders. Simply divide the dividend into groups that are multiples of your divisor and add up each of them to find your total quotient.

Alternately, you can also use the binary system to calculate numbers. A binary number uses only two digits (0 and 1) with an initial base of 2. This number system can be used both integers and fractions. A bit is defined as one binary digit while an entire word uses 16 bits.

Although there are numerous methods for converting decimal numbers to binary, you should always abide by certain guidelines in order to avoid mistakes and expedite the conversion process more easily and swiftly.

To convert decimal numbers to binary, first identify their smallest unit. For instance, if the decimal number 10 corresponds with two in binary terms, this means the unit of binary must also equal 2. Once this has been completed, search for the highest power of 2 less than or equal to that decimal number before dividing it by that power and finding out the remainder which represents your final binary number.


You will often need to convert binary numbers to decimal form for use. To do this, start by determining the values of each digit; for instance, 2 is considered the first digit here so divide by two first. After doing that, work out your exponent using both sign bits and magnitude bits.

Sign and magnitude are essential concepts in binary arithmetic because computers use them to represent negative values when representing them with computerized decimal arithmetic, unlike standard decimal arithmetic which uses plus and minus signs to represent positive and negative values respectively. A sign bit determines whether the number is positive or negative while magnitude bits determine how far to move the decimal point for correct results.

When converting from decimal, you can calculate an exponent by moving through each number digit by digit. For each one that begins with 1, multiply it by 2, before moving on to the next digit (if it begins with 0, move right and add one power of two each time you move right until all values have been added and you should have your final decimal form number).

Method two for calculating binary numbers involves using the doubling method, which works best when working with numbers having two bases. Simply double each number until it reaches your desired value and read off as usual thereafter.

This method can also be applied with numbers that use other bases; simply replace 2 with its equivalent in your calculations. Furthermore, you will require knowledge of its two’s complement form value – though its process varies slightly compared with others, the principle remains the same.

For this task, it is necessary to divide a number into two sections – whole number part and fractional part – then convert both sections to binary before working out an exponent value. Although this process may prove tricky at times, practice can definitely pay off!
