How does a binary number be presented?
Binary numbers start with a column with the value of 1 on the right side. The next column, to the left, has double the value (which is 2), the next left doubles again (which is 4), then 8, 16, 32, 64, 128 etc. The inclusion of a number 1 in a column means that the number should be included in the total. The inclusion of a zero in a column means that the number should not be counted. Using just this combination of 1s and 0s any number can be represented. For example...1 = 12 = 103 = 114 = 10010 = 101015 = 111165 = 1000001To convert the numbers from binary to decimal you can simply use a calculator and starting at the right side of the binary number if the first digit is 1 then add 1 to your calculator. If it is zero don't add anything, move left to the next column, if there is a 1 in this column add 2 to your total on your calculator, if it is a zero don't add anything, continue doing this, doubling the value for each column and adding the number if there is a 1 and ignoring it if there is a zero. For example....The binary number 1100, starting at the right has 0 in the 1 column, 0 in the 2 column, 1 in the 4 column and 1 in the 8 column, so you would ignore 1 and 2 and simply add 4 + 8, giving your a value of 12, which is correct.
What is 101 101 in binary?
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.
How do you multiply a number by two in base two?
Just add a zero on the right-hand end of it. ============================== Another contributor bloviated: Just the same as multiplying a number in base ten by ten : just tack a 0 on the end, Binary 11 (decimal value 3) multiplied by decimal two is binary 11 times binary 10 which comes to binary 110. In any base, multiplying by the value of the base tacks a zero on the end, because the value of the base, written in that base, is always 10.
How do you add negative numbers to positive numbers?
To add a negative number and a positive number: -- Find the difference of their absolute values (their sizes, ignoring their signs). -- Give it the same sign as whichever of the original two numbers had the larger absolute value.
