	Chickens and cows		2007-02-08
		From Norman: My grandson is testing me on a question he recently solved. The question is "A farmer has cows and chickens - there are 252 heads and 81 legs - how many of each animal does he have?" I immediately thought of the quadratic equations I learned 50 years ago at school, but cannot remember how to do it. It is further complicated by the fact that 1 animal must have 3 legs as the total number of legs is 81 (or perhaps he his trying to catch me out) Any helpful advice would be welcome. Many thanks Norman Answered by Stephen La Rocque and Penny Nom.

	BEDMAS solving for X		2007-02-07
		From damian: Hi, I am having a problem understanding why when using BEDMAS the text book example of the following question has used bedmas and reduced the calculation to 4/3. Text book formula: X/200,000 = (X - 90,000) / 150,000 X = 4/3 * (X - 90,000) X = 360,000 My solution: I always thought that when you do something to one side you do the same to the other. Why would the equation bring the 200,000 / 150,000 down to 4 / 3 I would think it would look something like this. X/200,000 = (X - 90,000) / 150,000 X = 200,000*((X - 90,000) / 150,000) Answered by Stephen La Rocque.
