Negative Subtracting Problems

Posted in Math at 5:30 am by Kitten

This story is told in letters, for it is in letters that it happened.

I tell you what I think was happening right before the letters began:

One morning, in the world of Backwards Math (a small land inside a bigger land called MathLand), a little number named -1 + – 30= -31 went to check his mailbox and found a letter. That letter begins our story of letters.

Dear -1 + -30 = -31,

-70 – -40 = ?  needs you to help find her answer!!!

Please help!!!

-40 ÷ -20 = 2

Dear -40 ÷ -20 = 2,

Tell -70 – -40 = ? to shorten -40 to -39, then she’ll get -31,

then subtract -1 and there’s her answer.

-1 + -30 = -31

Dear  -1 + -30 = -31,

-70 – -40 = -30 found her answer, thanks to you.

She doesn’t know how she’ll ever be able to repay you,

-1 + -30 = -31.

-40 ÷ -20 = 2

Dear  -40 ÷ -20 = 2,

No prob. I loved helping her.

-1 + -30 = -31

I think that -1 + -30 = -31 came to the level of being called -31 soon after. (Because of how well he handled the problem.)

And so this story of  letters is told. I hope that soon I’ll be able to tell you another.

Math games for learning Times

Posted in Math at 3:51 pm by Kitten

If your child is having problems learning multiplication, then the best way to teach them is to make it fun and to help them solve the ones they have trouble with. There’s a website you can go to that makes it fun. You still need to help them with the harder ones, and I’d be careful on the games you start them on, so that you can change the level if you need to, but it’s still very fun.

Click here to go to Interactive Games and get your kids in the times.

I liked it a ton, but stick to page 1, because the games on the other pages take you to different websites. (Though I guess you might like them, how should I know? We tried one, and it wasn’t as good, because you have to go real fast, and I don’t like games that are timed.) Hope you like it, too!

Backwards math

Posted in Math at 1:48 pm by Kitten

So I’m not usually really into math, but now that can just rest when it comes to this kind of math. Well, you can’t blame me — I mean I’m the one who invented it.

Basically my thing to do, in math anyway, is backwards math. It’s done down in the negatives. My mom wrote an article on how it happened, and a lot of people liked it.

Here’s a few samples of it:

-15 - -10 = -5

-15+-10=-25

-6 \times -2=12

That’s the three different kinds that I know. Times (the last one) I had to learn. It’s really hard to figure out what the answer is, if you don’t know how to do it.

You can teach backwards math to your kids to see if they like it better then normal math. They probably will — though you should think about the age of your student, because Mom said that it was pre-algebra work. Though that might be why I like it, because I like algebra, too.
