To be perfectly honest I don't know how your other computer works because I have not had one of that type before.

Perhaps Bob has an idea. I have sent you an email just a moment ago.

hi Mandy,

If you subscribe to the thread, you will get an email when someone posts. See picture below.

Some email programs will make a beep on your computer when new mail arrives.

What are you using for emails?

Here are a few problems that I have made up for you to look at and attempt when you are ready:

Problem (1)

£490 is put in a savings account for a year with a rate of 3%

No money is taken out and no more is put in during the year,

and the amount of interest paid is exactly 3%

How much does the person receive in interest ?

What is the total amount after this is added to £490 ?

Problem (2)

Am amount of £160 plus VAT is quoted by a supplier.

The VAT rate is 20%

How much is the 20% VAT ?

How much is the amount after adding VAT ?

Problem (3)

It is said that Oliver is 10% taller than Jack.

Jack is 170cm tall.

How much taller is Oliver than Jack ?

How tall is Oliver ?

You may of course use your calculator for these.

My answer to problem (1):

£490 is put in a savings account for a year with a rate of 3%

No money is taken out and no more is put in during the year,

and the amount of interest paid is exactly 3%

How much does the person receive in interest ?

The percentage 3% should be regarded as three of one hundred equally divided

parts of the amount. So we could divide £490 by 100 to give us £4.90 and then

multiply by 3 to give us £14.70. If you are using a calculator this is a rather

slow way round things, but at GCSE level you would be expected to understand

both methods:

So either 3 x 490 / 100 = 14.70

or with a calculator you can do this: 0.03 x 490 = 14.70

£14.70

What is the total amount after this is added to £490 ?

This is just a simple addition. Care must be taken to line up the

decimal point if you are using pen and paper for this, but using

a calculator you just have to be careful with typing the right keys:

14.70 + 490.00 = 504.70

£504.70

My answer to problem (2)

Am amount of £160 plus VAT is quoted by a supplier.

The VAT rate is 20%

How much is the 20% VAT ?

If you are doing this in your head or on pen and paper you could convert

20% into a fraction by regarding it as 20 parts of 100 equally divided

amounts which cancels to one part of five equally divided amounts.

You could then work out 160 divided by 5 which is 32.

When using a calculator I would just write:

0.2 x 160 = 32.00

£32.00

How much is the amount after adding VAT ?

This is just an addition of 160 + 32 = 192

£192.00

My answer to problem (3):

It is said that Oliver is 10% taller than Jack.

Jack is 170cm tall.

How much taller is Oliver than Jack ?

10% is equivalent to 10 parts of 100 equally divided parts.

It is therefore the same as dividing by 10.

So you could do 170 / 10 = 17

Or with a calculator you could do 0.1 x 170 = 17

17cm

How tall is Oliver ?

Obviously just add on the 17 to 170 being careful about place value.

170 + 17 = 187

187cm

I have inserted new figures into this in an attempt to make the amounts closer to reality ... however they are of course

made up prices and electricity usage amounts to illustrate the general idea of how the calculation might work.

Yes, I know,

You seem to be dyslexic but I believe that with determination, you'll be able to do math too and behave like normal

Either way whether you consider it to be 'dyslexia' or 'dyscalculia' if you are managing to get two numbers round the wrong

way as a result of the developmental condition both in terms of interpretation and your own writing, then some answers to

maths problems will end up being wrong in the same way as with answers to a spelling test.

You have, in some of your answers, showed signs of having the right general idea, but showing signs of the sort of mistake

that I would imagine that someone with dyslexia would make. For instance when you divided by 10 instead of multiplying by 10

once or got the decimal point in the wrong place. On the other hand you went on to getting about 10 of those right in a row.

The are a lot of maths problems that would be an absolute nightmare if those numbers are appearing to 'jump' so to speak when

you are reading them, or the sign is unclear, or the operator is easily muddled between multiply and divide etc.

Both dyscalculia and dyslexia are developmental, there is no cure to either of course, and the best a person can do that has them

is to self manage the problem well, find workaround solutions, and pursue things where the disability does not matter very much

eg. creative things (art, music, drama, etc. ).

If you do have a specific real life maths problem that happens a lot that you cannot do then please do tell us what it is.

Another two things have occured to me:

If I write this: 69 96 52 25

Does that appear clearly as "sixty nine, ninety six, fifty two, twenty five" if it does not then I should think that it could

well be best thought of as 'dyslexia' or something similar. Obviously this does not prove the matter, and I am not qualified

in this area so I may be getting confused, but I am assuming that for you those numbers are hard to read.

Also: Presumably as is natural you don't like to do something if it seems impossible. That is to say: in order to be motivated

to do something you have to believe that it is a realistic task. I am assuming that GCSE maths problems for you are not a

realistic task. So: Can you set yourself a challenge that is a realistic task instead. Obviously that is a personal thing and

not an absolute. I have tried to set problems of the right level. Focusing on the real problem at hand is better. That is why

I wrote that you could tell us of a real maths problem (perhaps with the details changed to avoid revealing any information

that is not suitable for the internet due to privacy reasons) that you could be helped with. Or perhaps maths is a bad idea

anyway in your case. Then again quite a lot of things use maths.

According to wikipedia dyscalculia is:

"difficulty in learning or comprehending arithmetic, such as difficulty in understanding numbers, learning how to manipulate numbers, and learning maths facts...."

whereas dyslexia is:

"characterized by difficulty with learning to read fluently and with accurate comprehension despite normal intelligence. This includes difficulty with phonological awareness, phonological decoding, processing speed, orthographic coding, auditory short-term memory, language skills/verbal comprehension, and/or rapid naming"

Therefore my conclusion is if you are finding the maths difficult to read and interpret then it is dyslexia (if either).

However if it is the understanding of numbers and how to manipulate them then if either it is dyscalculia.

As for learning maths I agree with what Agnishom was saying about being determined to succeed.

It is important to stay motivated if you are trying to learn something.

Let us work on the assumption that it is 'dyslexia' that you have. You might of course have a bit of both.

Whatever you do (if you want my advice) don't waste any money on the issue.

Hi Mandy Jane;

There is an online site that will try to determine the question of whether you have dyslexia or not. You will need someone to sit next to you while you take the test. It is supposed to be free so do not pay anything.

See you later, I have to go offline here.
