The base 12 number system is more like the base 5 number system versus the base 10 number system, there are just more numbers involved (number values). This number system uses 12 different values; 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, T (10), and E (11). The reason why 12 is not used is because once you get to that value, you move to the next placement value. The placements are one's, twelves, one-hundred forty four, and so on. The placements are also known as the powers of 12. For some background information on this system click here.
The number 236 base twelve is actually the number 330 in base ten. You get this answer by multiplying 2 by 144, adding that to 3 times 12, and then finally adding that to 6 times 1. Lets try another one... the number 5T1 base twelve would be 841 base ten. Remember, multiply 5 by 144, add that to 10 times 12, and then add 1 times 1.

Ok so T is Ten and E is eleven I will not forget it.
ReplyDeleteThe T's and E's emmbedded in numbers get me cofused too! I will have to remember
ReplyDeleteYour blog reads to me almost like a dictionary definition, but more like a Wikipedia definition. The block text format you've created shows very little about the elements of base twelve, and its stress in possitionality.
ReplyDeleteYou may be better able to express the elements mentioned, "The placements are one's, twelves, one-hundred forty four, and so on" if you were to use more space in the orientation of your lesson.
Thank you for explaining this so well.
ReplyDeletei'm sorry i didn't understand what these blogs were about. youre blog is actually very concise.
