Wow!

Last year I started composition books with our two youngest. They each have their own. I would write a question and they would answer it. Then they returned it to me with a question. I answered, wrote another question, etc. (A sneaky way to get them to write.)

It was very interesting. They would ask some hard questions. And give some revealing answers.

This year I decided to use the books for math. I will give them problems to work and they will return the favor. I enjoy math but I figured sooner or later they will stump me. Sure enough Christopher went online with the search line, "hard word problems".

He got one for me that went clean over my head. I studied it awhile and decided to see where he got it. No help there except for the info, "Most tricky and tough algebra problems are covered here." Yikes!

Determined to master this, I searched for how to solve algebraic problems. (I'm the person who, if you tell me it isn't likely to be done, I'll master it. I was told in my younger days that, "Girls can't whistle with a blade of grass." Wrong thing to tell ME!)

So I settled down to GET THIS! I followed a couple tutorials online until it finally got through my head. A few simple steps and presto! There was the answer! Christopher said he hasn't seen me so excited in a long time. Well, I was! I can't describe the feeling of empowerment that came from mastering that problem.

And a piece of info I left out above from the "hard problems site"- "If you can solve these, you can probably solve any algebra problems." Obviously there are lots more on that site but to tackle and conquer something that seemed so impossible, was fantastic. Maybe I can do it again.

It was interesting to me how that feeling stayed with me even in other matters. Where something would before look impossible, I'm thinking, "Maybe I could get this!"

Here is the problem in Christopher's handwriting (he writes very faintly in pencil) and also copied and pasted from the site-

The cost of petrol rises by 2 cents a liter. last week a man bought 20 liters at the old price. This week he bought 10 liters at the new price. Altogether, the petrol costs $9.20. What was the old price for 1 liter?

Can you solve it?
