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.
Each place value in a binary number represents what?
A power of 2. In the decimal system, we use powers of 10, in the binary system, powers of 2. Other number system use some other number as their base; for example, hexadecimal (base-16) uses powers of 16.
In the following write the binary number in base 10. 1001111 base 2?
Binary 1001111 is 79 in decimal.
What is the base 10 value for the binary number 1101 with subscript 2?
(1 1 0 1)2 = (13)10
What is the binary number 1000 in base 10?
The binary number 1000 is the decimal (base 10) number 8. The digits in a binary number are exponents of 2 rather than 10, so that for a four-digit number in binary, the digit places represent 8, 4, 2, 1 1000 (binary) = 8 + (0x4) + (0x2) + (0x1) = 8
