But the reason the student and I did so well is we learned it together and we had fun.

So the book is this: The Math Myth: And other STEM delusions by Andrew Hacker

The article about the book had an equation: (y + -3) x 2 = 4y - 12

I solved using my own rather strange way. Did I get it right? Well, I looked it up. And yes, I did, but OMG! No wonder kids get discouraged!

Simplifying [y + -3] * 2 = 4y + -12 Reorder the terms: [-3 + y] * 2 = 4y + -12 Reorder the terms for easier multiplication: 2[-3 + y] = 4y + -12 [-3 * 2 + y * 2] = 4y + -12 [-6 + 2y] = 4y + -12 Reorder the terms: -6 + 2y = -12 + 4y Solving -6 + 2y = -12 + 4y Solving for variable 'y'. Move all terms containing y to the left, all other terms to

the right. Add '-4y' to each side of the equation. -6 + 2y + -4y = -12 + 4y + -4y Combine like terms: 2y + -4y = -2y -6 + -2y = -12 + 4y + -4y Combine like terms: 4y + -4y = 0 -6 + -2y = -12 + 0 -6 + -2y = -12 Add '6' to each side of the equation. -6 + 6 + -2y = -12 + 6 Combine like terms: -6 + 6 = 0 0 + -2y = -12 + 6 -2y = -12 + 6 Combine like terms: -12 + 6 = -6 -2y = -6 Divide each side by '-2'. y = 3 Simplifying y = 3

THIS is only ONE reason I hated math...

I saw the warning and I STILL came in here.

Now my head hurts!

Solve for 'y', you ask? Why? Indeed!

i love this post

that is all

I'm with anne marie and Bob! My head hurts! Math never was nor never will be my forte`. Loved geometry though.....

I look at what my (young) grandkids are learning in their math class and I scratch my head in wonder! What is the world coming to!

You lost me at math. =)

I hope they fix this mess before Kyle gets too far along. He loves it right now, and this stuff is just going to frustrate all of us.

He owes you a thank you card, but he loves the book. He's going to have a lot of fun reading it.

Brain...hurts....

Like Bob I saw the time yet still read the post. Wow I didn't know the trauma from high school would resurface so early in the morning.
