Yes that's fine.
See you on Sunday.
I know this is a difficult one, but how about 12.1 - 0.589 ?
(I need to know whether you can do the 1.3 - 0.716 question though, if you can't do that one then you
won't be able to do the one above.)
Of course you can ask questions and add posts in between now and Sunday and we could exchange a few
posts at disjointed times. You have done these questions better and more quickly than I had thought you would.
I could do with knowing whether you want to do multiplication and division and what sort of question.
You are almost there with subtraction already and at the rate you did those other questions it shoudn't take very
long. I found it difficult to keep up and I was the one setting the questions.
Just to test you as to what you know already how about:
3.46 x 7 ?
3.46 x 0.7 ?
1.89 divided by 7 ?

I think we need to finish off the subtraction bit. I will do 1.3 - 0.716 as an example:
It is helpful to add two extra zeros on the end of 1.3 - this does not effect what the number actually
is and enables us to line up the two numbers correctly:
1 . 3 0 0  -
0 . 7 1 6
----------

----------
Now 0 - 6 won't work because it is a negative result. Looking to the left the next number is a
zero so that is no good. Looking to the left again we have a "3", we can reduce this to 2 and
drop a 9 to the right instead of the first zero and increase the second zero to ten.
So we end up with something like this (of course there will be a few crossings out in a hand written
test or assignment - the 3 and the first 0 are crossed out in this case).
1 . 2 9 [10]  -
0 . 7 1   6
-------------
        8   4
-------------
Note that I have filled in the two numbers 4 and 8 which are now easy to work out.
Now 2 - 7 is going to be negative as well so let's borrow from the 1 to the left.
The 1 at the top left gets crossed out and replaced by a 0.
Then we have to add 10 to the 2 because this is worth ten times as much in this column:
0 . [12] 9  10
0 .  7    1    6
-----------------
0 .  5    8    4
-----------------
As you can see I have finished off the answer. 12 - 7 is now easy. The left most column is
very easy 0 - 0 = 0 .
Notice that I have added the decimal point being careful to get it in the right place.
If you so wish you could do 12.1 - 0.589 as a similar problem to check that you have
understood what I have explained.
It would be interesting if you post it to this site or via email so I can see if you are correct
and doing it correctly and I will help if you need some help.
I think we had better delay the multplication and division for a bit. I was jumping ahead a
bit because I thought that you were coping very well with the addition.
You can of course make up your own examples and try them to see if you can do them
check them with a calculator and obviously if you have managed to find something that
you are stuck on by all means post it here or email it to me. Practice is a good way to
learn some basic maths. You cannot learn maths as you might read a novel.
I do entirely understand about your dyslexia. If you cannot do times tables from 2 to 9
then you will not be able to do multiplication and division very well. We need to discuss
this a little and it might be better if we discuss that and a few other things about what
other topics to deal with etc. we can discuss this via email if you prefer.

Hi anonimnystefy. Thanks for your welcome post.

Yes that's fine.
It looks like I am going to be in for more of today than I previously expected.

hi mathgogocart mandy here. how do you think i am doing with my maths then? send message back please?

Good.What do you want me to teach?

Right. How about I do that instead. Now 1.3 - 0.716 ?

It can be set out like this:
1.300 -
0.716
------

------
0 - 6 will give us a negative number. So what do we do ?

Whoops! Sorry about that I have got two subtractions muddled in my head.
I meant to ask about the one that went 12.1 - 0.589
I have already done a worked example for 1.3 - 0.716
However if you did not read the worked example (Mandy) then you could still have a go.

Hello (Mandy) I have noticed that you are logged on....

Hi steveb mandy here. 1 1 3.  7 0 0
                                  0 6 6.  3 2 8
                                  ---------------
                                   0 4 7. 3 7 2
                                   --------------
Is this correct then?  Can you post long division now for me to preview please?

Hi bob bundy mandy here. -do you think my maths is going then?

Now a slightly harder one on long division, but still fairly easy:

     0 6 3
    ------
7 | 4 4 1
     0
     -
     4 4
     4 2
     ---
       2 1
       2 1
       ---
       0 0
       ---

Each time we choose the highest number below or equal to the remainder
added to the number dropped down, in the times table of the number we
are dividing by.

[ 0, 7, 14, 21, 35, 42, 49, 56, 63 ]

So for example if the number we are left with is 44 after a 4 is put on
the end of remainder 4 then as you can see 42 is the number in the 7 times
table to put under 44.

If we put anything smaller down say 35 then it would go wrong because we
would end up with the remainder being too high - eg. 44 - 35 = 9
this is too high because with a division by 7 each remainder needs to be
in the range (0, 1, 2, 3, 4, 5, 6).
If we choose the multiple of 7 to be 49 with 44 as the number left, then that
would be too high because the subtraction is 44 - 49 = -5 which is too low
to be in the range (0, 1, 2, 3, 4, 5, 6).

I must admit that long division when I was taught it at school was intended
for dividing by a number of at least 13 so perhaps I should do a more
advanced example next.
