55. 101 in binary is 5. there is a shortcut in getting the equivalent in binary. 421 if it is 1, then it's 001. if it is 2, then it's 010. if it is 3, then it's 011. if it is 4, then it's 100. if it is 5, then it's 101. see? you just have to add the numbers that you need. you'll write 1 when you used the number that is needed and 0 when not.
The number you have given = 74 not to sure what you mean by add a sign to it. To make 75 the number would be 1001011
An odd number of odd numbers can not add up to an even number. There fore any 9 (odd) odd numbers can not add up to 50 (even).
83, 3,and 2 are prime numbers which add up to 88.

There are a few rules to perform arithmetic operations in binary numbers. According to those rules you can add or subtract binary numbers. There are only two arithmetic operations used in binary numbers, they are addition and subtraction.
Adding the numbers 1011 and 1101 in binary gives 11000 - equivalent to the decimal number 24.
1010110= 86 1011010= 90
If you want to add numbers in different bases, in this case decimal and binary, or do any other calculation that involves different bases for that matter, you have to convert all numbers to a single system first - for example, all to decimal. Then you can do the operation. It is really up to you in what base you represent the final answer. In this example, you can convert back to binary, for example.
To do addition or multiplication with binary numbers, you basically use the same method as for decimal numbers. Just remember the basic addition facts, for example: 1 + 1 = 10, 10 + 1 = 11, 11 + 1 = 100, etc.
i have the same question. please some1 answer it...
To count in binary it is relatively simple. I will count in 8-bit, what this means is there will be 8 binary digits as a result. To get the values for each of the 8-bits you will need to set the first bit as one and double 7 times for each of the values. In this case the numbers will go: 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 (The numbers must go from large to small) These are the values that will be used in our counting process, we add them together to get the numbers we want. However, computers don't understand those values (I am assuming that you know that a binary digit can be only 1 or 0). To get the number 3 in binary, we need to add 1 and 2 from the list above. So we will switch the numbers 1 and 2 on (on = 1, off = 0), so the number 3 in 8-bit binary will be: 00000011(11 for short) You can do this with any number up to 255 (11111111) and then you will have to add more bits by doubling 128 and so on. Here are the numbers 1 to 10 in binary: 1 (1) 10 (2) 11 (3) 100 (4) 101 (5) 110 (6) 111 (7) 1000 (8) 1001 (9) 1010 (10) If you are struggling to understand this, get some paper and write the numbers seen at the top of this answer. Then underneath them put a 1 if you need to add that number to make the result and a 0 if you don't. This makes it a lot easier to work out.
19) Add an 8th bit for the following binary numbers to act once as an even parity and another time as an odd parity. i 1010001 ii 1111000
-8
I assume that you are asking how to convert the binary: 011110 to decimal. First off there are 6 places in this binary number--actually five, being that the last number is 0 (a place-holder). So, charting or making a table: Binary CalculationDecimal EquivalentOriginal Binary NumberAdd together2010021212224142381824161162532002664Not givenNot given Add together the last column of numbers together will give you the decimal equivalent to the binary number: 011110.
0 + 0 = 0, 0 + 1 or 1 + 0 = 1, 1 + 1 = 1 and carry 1. If you are adding more than two binary numbers, an even total = 0, an odd total = 1. Remember carries!
