Re: Mandy Jane's Corner

Yes, there is no point in worrying. Just makes wrinkles. I do not want you to change, just be happy with what you are.


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Mandy Jane's Corner

hi Mandy

You have the user manual I hope.

Unfortunately, the manual is not available on the Canon website, so it will be harder to advise you.

But it looks much like most scientific calculators so I should be able to help you as and when you need it.

What colour is it?  I'll make a picture of one so I can point at the right buttons.

Re: Mandy Jane's Corner

I've made a picture of your calculator.  It started black but I've changed it to green so it looks like yours.

When you have a query about how to use it, I'll be able to show you in a picture which buttons to press.

Because I don't have a manual, I may have to guess sometimes, so it might take more than one post to get there, but I'm sure we will.

Do you want to try something on the calculator?

Re: Mandy Jane's Corner

OK, let's try squaring numbers.

eg 3 squared means 3 x 3

But we will try the square it button.

In the picture I've shown which button this is.

So do this

What answer did you get?

Re: Mandy Jane's Corner

Correct.

let's do all the square numbers from 1², 2², ........, up to 12².

Use the x² button for these.

Post back the 12 answers.

(I'm trying to do the washing up, then back to the computer to answer your next post, so don't think I've gone if you have a longer wait for my reply.)

Re: Mandy Jane's Corner

Excellent!  All correct.

I have made a screen shot to answer your question about the little 2.

Now let's try doing some square roots.

The square root button does the opposite of the square button.

eg  √144 = 12.

Try it like this.

I'm pretty sure that on your calculator you have to press the √ button first, then 144, then =

Do you get 12?

If so, try square rooting 144, 121, 100, 81, ......1 to see if you get the original numbers back.

Re: Mandy Jane's Corner

Well, you know you are right don't you?  Squaring a square rooting are opposites.

Try this.

Choose any number you like and square it.

Start with that answer and square root it.

You should be back to where you started.

Tell me what number you chose, and what it was when squared, and what that became when square rooted.

The symbols at the top of the page can be copied.

So highlight the ²  ,  then press CTRL and C together to copy.

Go to your text where you want the symbol and press CTRL and V together to paste the ²

You can also copy it from this post in the same way.

Re: Mandy Jane's Corner

Yes, we have had rain for most of the day.  I'm watching Springwatch.  The reserve in Wales has been devastated by the rain.

So what work still needs to be completed?

(1)  Do all corrections in your assignment Q1 and Q2.

(2) Do that fractions question.

(3) Check out the prime number lists.  Are the two lists the same?

One last question:  How are you with times tables?

Re: Mandy Jane's Corner

I have a program that tests you on your tables.  When I have got pupils to use it regularly they gradually get better and better.

I think it will help you as you will be able to do long multiplication more easily.
