what is ten in hex?

Question

for the best answer i would like a brief description of hexidecimal in laymans terms.

Answer 1

Our standard number system is base 10, meaning we have the numbers 0 - 9. Hexadecimal is base 16 - meaning it has the numbers 0 - 9 then the letters A - F. 10 in hex is A, as this comes straight after 9.

Answer 2

You know, I've read the other answers, and the one thing nobody else has touched on is how the next decimal places are derived. They are all powers of the number whose base you're working in. For example, in base 10, the ones are actually expressed as 10 to the 0 power (which this little word processor won't let me write properly). The 10's are 10 to the 1st, hundreds are 10 to the 2nd (or 10 X 10), 1000's are 10 to the 3rd (or 10 X 10 X 10), and so on. You don't get to move over a decimal place until you've used the smaller place up. In base 10, then, 32 means there are 3 X 10 to the 1st power (10's) plus 2 X 10 to the 0 power (1's). 132 means you have 1 X 10 to the 2nd power (10 X 10, or 100), plus 3 X 10 to the 1st power (10), plus 2 X 10 to the 0 power (1). Okay -- so in hexadecimal, the first place is 16 to the 0 power, which is always 1's, no matter what the base is. The 2nd place over is 16 to the 1st power, which is 16's instead of 10's. The second place over is 16 to the 2nd power, which is 256's instead of 100's. The third place over is 16 to the 3rd power, which is 4096's instead of 1000's. In hexadecimal, then 32 would be written as 20 (2 X 16 to the 1st power). 132 would be written as 84 (8 X 16 to the 1st power, plus 4 1's). 140 would be written as 8c (8 X 16 to the 1st power, plus 12 1's). 332 would be 14c (1 X 16 to the 2nd power, plus 4 X 16 to the 1st power, plus 12 1's.)

That's about as layman as I can make it. I suppose if we all had sixteen fingers, it'd be easier. I'm going to stop making my own brain bleed now, and go do something about dinner.

The decimal system is also known as a base 10 numbering system, the reason why is you have 8 "numerical values" to work with which are 0 - 9. Hex on the other hand is a base 16 numbering system, in which the "numerical values" are 0-F, with F being the highest. It’s not really hard once you think about it.

Answer 4

To answer your question the Hex value for 10 is A, now let me explain how you get that. Decimal values that we count in is base ten, the numbers 0-9 being the ten numbers put in different combinations to make our number system. We go 0 to 9 and than carry one to the next value point to make the next number 10. Hexadecimal values use the same kind of system, only it uses base 16. It's numbering system goes 0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F. So you would count 1 to nine like you would in decimal, A would be ten, B, would be eleven, and so on. Once you reach F which is 15 you carry over. 10, 11, 12,13,14,15,16,17,18,19,1A,1B,1C, etc. You would go this way until you hit 9F. At this point it would go 9F, A0, A1, A2, A3, A4, etc. That is how you count in Hexadecimal. To convert Hexadecimal to Decimal would be a different process which you would have to look up about, it would take too long to explain in an answer. Hope this helps and good luck learning Hex.

Answer 5

Ten in Hex = A

From Wikipedia

"In mathematics and computer science, base-16, hexadecimal, or simply hex, is a numeral system with a radix or base of 16 usually written using the symbols 0–9 and A–F or a–f. For example, the decimal numeral 79 whose binary representation is 01001111 can be written as 4F in hexadecimal (4 = 0100, F = 1111). The current hexadecimal system was first introduced to the computing world in 1963 by IBM. An earlier version, using the digits 0–9 and u–z, was used by the Bendix G-15 computer, introduced in 1956."
