Let a=b.
a^2 = ab
a^2 + a^2 = a^2 + ab
2a^2 = a^2 + ab
2a^2 – 2ab = a^2 + ab – 2ab
2a^2 – 2ab = a^2 – ab
2(a^2 – ab) = 1(a^2 – ab)
2 = 1

and
2 + 1 = 1 + 1
3 = 2 = 1 and so on.

PS: the joke is that it stumps most high schoolers.

I’m a 3rd year at the moment, and if I look around an average lecture, I tend to see a split of about 75/25 boys to girls. Next, look at PG level – you get very few girls – I know quite a number of Postgrads, only 1 of whom is a girl, so I would suspect a 90/10 split. At Professor/Doctor level, this split seems to be even more acute, looking at the staff for the Department – I can only think of 1 female lecturer or faculty member off the top of my head, and I know most of the department since I’m president of the Maths Society.

Now, obviously it’d be great to see more girls take maths at Uni level (my girlfriend is a great example of this), but I think it’s another challenge all together to get girls to take the study to Doctorate/Professorship level.

In the R.O.P. programming class, we had almost as many girls as boys. Our teacher was a female, so that helped tremendously. The competition during assignments was always girls vs. boys. Happily, we tended to match or outdo them!

I applaud anyone whom attempts to take on something that society has continued to turn a blind eye to. Why do Mothers continue to teach their Daughters, either by choice or example, that college is for ‘finding a husband, or, to take a major that is considered ’safe’?

Kudos to Ms. McKellar!!

Mothers can’t give what they don’t have to their daughters. Most mothers are Math-challenged!

You want girls to get interested? Get the mothers interested!

Perhaps a free program to teach mothers basic Mathematics could help.

Mothers could progress from basic math to middle level and beyond, so that they can acquire enough math skills to help their daughters with homework.

With a better understanding of Mathematics, mothers could turn activities like shopping, banking(going to the bank)and even cooking into math-teachable moments.

i came up with this last year when i was in my english class bored……except tht i used straight like this

1=1

1^2=1*1

1^2-1^2=1*1-1^2

(1+1)(1-1)=1(1-1)

(1+1)=1

2=1

urs is lil dif. way but same

i also found tht this way you can start with any number and end up with equal to the number twice as much……

who r u?

email me at nishu111992@yahoo.com

and im only 15, but how old are u?

im sorry but it would just annoy any1 if there works been stolen or odly been used by someone else that took time for.

number can be made equal to any other

number.

Since a=b => a^2 – ab or a-b is zero.

a=b

a^2 = ab

a^2 – b^2 = ab-b^2

(a+b)(a-b) = b(a-b)

(a+b) = b

a+a = a

2a = a

2 = 1

You cannot divide by a-b which is zero.
