Yes so you could put them all in one addition if you wanted. Like this
1 . 7 8
2 . 8 9
3 . 6 7
---------
---------
If you had three things to add together like 1.78 + 2.89 + 3.67 what would you do ?
Sorry about that I realise that you have posted at about the same time that I posted that.
Yes well done you are correct again.
3 . 5 7 +
6 . 6 9
-----------
----------- ???
Yes well done. Correct.
Right how about 3.57 + 6.69 ?
OK here is the problem:
5 . 7
3 . 6
--------
--------
What is the first step in solving this addition ?
OK here is what I suggest. How about you try an example like 5.7 + 3.6 and see how you get on with that.
By the way the answer 6.1 does have a decimal point in it. (Bob left this out of his graphic)
So:
2 . 6 +
3 . 5
--------
6 . 1
--------
1
In the next column the addition is 2 + 3 (which would usually be 5), but there is one to carry meaning that 6 goes in the answer.
2 + 3 + 1 = 6
OK ?
Right now I need to get an idea of how well you understand this already.
Look at the right hand column of the addition. You will see that clearly 6 + 5 = 11 and that the "units" bit of it has been put
into the answer box as "1". Under the addition a "1" has been carried.
Hello Mandy (if you're there). Right shall we look at Bob's post about his 2.6 + 3.5 example ?
Right I am just about to send another email....
I have now received two short emails from you. I have sent two short replies confirming that I have got them.
However I get the impression that you are not getting the emails that I have sent you. Have you got any of
the emails that I have sent you? Do you think that I can best help you on this website or by email?
Ah-ha I have just received your email Mandy. I will try replying to it.
My email to Bob has got through and he has replied and that has got through.
Your email that you have just sent has not got through.
So I think we will have to discuss things on this website instead.
There are several sub topics that occur to me to do with decimals such as:
(1) Rounding (eg. round 3.54, 2.78 and 3.17 to 1 decimal place)
(2) Putting numbers in the right order (eg. 3.06, 3.60, 3.006, 3.0606)
(3) Arithmetic using decimals (add, subtract, multply, divide)
(4) Understanding things like that 0.01 is ten times as big as 0.001 and other things to do with place value.
I have read your last post, but I still don't know why these emails are not getting through.
I have thought that it might be a problem with our ISP. I could try sending an email to Bob
to see if he gets that.
Hi, I have sent another email - just a short one this time with the title "Test Email".
Quite frankly if you haven't got that one then something strange has happened.
I have now sent you 3 emails.
I'm not sure what has gone wrong, but I have sent you (Mandy) an email. (As asked by you and Bob)
I have checked the email address and it is correct.
