tonyman Posted July 25, 2013 Share Posted July 25, 2013 My daughters just asked me to try and help her with this , ive done so much with her (on other pages too ) but come to a halt at this stage , can anyone help ASAP .......thanks Link to comment Share on other sites More sharing options...
Notts Posted July 25, 2013 Share Posted July 25, 2013 The earliest number (nearest the top) should be 30, so that 30 divided by 2 is 15 - she has 15 divided by 2 rather than 15 as the answer. Link to comment Share on other sites More sharing options...
jodipodi Posted July 25, 2013 Share Posted July 25, 2013 tonyman is it not meant to be the opposite when going back?.....as in 14 - 1 rather than 14 +1........have a look......I could be wrong but I think theres a mistake and possibly where its gone skewiff......maybe elsewhere too.....please don't shoot me down if Im wrong though ?

MicheleW Posted July 25, 2013 Share Posted July 25, 2013 You have a calculation error in the 2nd from bottom row in addition to the error mentioned previously Link to comment Share on other sites More sharing options...
lebourvellec Posted July 25, 2013 Share Posted July 25, 2013 You've gone wrong second line up where it's -9 answer should be 16 Link to comment Share on other sites More sharing options...
BritChickx Posted July 25, 2013 Share Posted July 25, 2013 bloody hell that's giving me a brain ache, can tell i've not done maths for years lol. nevermind i get it now lol Link to comment Share on other sites More sharing options...
jodipodi Posted July 25, 2013 Share Posted July 25, 2013 I agree with MicheleW...... 7-9 done backwards is 7+9...... Link to comment Share on other sites More sharing options...
Guest51810 Posted July 25, 2013 Share Posted July 25, 2013 Can she help me with mine lol Link to comment Share on other sites More sharing options...
jodipodi Posted July 25, 2013 Share Posted July 25, 2013 If I was doing this with my own Id suggest they write in with pencil the 'opposite' sign above and then do the homework, then rub out said pencil marks might help as this is so easy to get muddled Link to comment Share on other sites More sharing options...
welljock Posted July 25, 2013 Share Posted July 25, 2013 Not going to go the whole way through it but a few mistakes the box with -2 above should be 16 then 8,8,5,2,10,17,24,6,2,8... giving up there as I keep losing track scrolling up and back Link to comment Share on other sites More sharing options...
BritChickx Posted July 25, 2013 Share Posted July 25, 2013 the first set of boxes going from right to left I got 7-5-4-2 minus 2-minus 4 and if i havent got it right im a dumbass! lol Link to comment Share on other sites More sharing options...

Levi Posted July 25, 2013 Share Posted July 25, 2013 At times like these I wish exercises like this one were given at interviews, because I would ace them. Instead they ask me 'What is your passion?' and other crazy stuff, at which point all I can do is cry. Link to comment Share on other sites More sharing options...
tonyman Posted July 25, 2013 Author Share Posted July 25, 2013 so can you fill it in for me Levi or do we need an interview first ......? :wink: Link to comment Share on other sites More sharing options...

Levi Posted July 25, 2013 Share Posted July 25, 2013 You know why I like the English language so much (and read in English a lot, and write and speak it so well)? Because there are times when I can say "Read'em and weep." 7 14 13 26 20 21 7 14 10 7 16 8 8 5 2 10 17 24 6 2 8 5 45 15 14 20 16 8 -2 6 5 10 2 8 24 72 63 9 18 15 12 10 9 18 6 2 16 25 100 20 18 9 27 35 7 0 0 4 8 1 1 4 12 60 30 21 3 10 18 26 13 18 6 -2 9 3 6 12 24 13 5 30 10 8 12 17 15 5 20 17 Now I'm just hoping that it's error free. Guess your daughter will find out! (Joking aside, I tried my best and think these are the correct numbers.)

Bobbsy Posted July 25, 2013 Share Posted July 25, 2013 Boring old git rant coming up... I was GOOD at math 50ish years ago and, with lots of concentration can work that out--or can if I zoom my screen in far enough to tell the difference between the division sign and the plus sign. However, I can't for the life of me work out what practical maths a problem like this is trying to teach. Strikes me that it's much more an exercise in concentration than actual mathematics. I can see the beginnings of this kind of thing in the maths homework that comes home with my eight year old. They haven't bothered doing any exercises in memorising times tables or whatever but, instead, get brain teasers like this one (though a bit simpler). What's wrong with learning the basics instead? If this is the maths of today I can see why people working on check outs can't work out simple change without a calculator. Link to comment Share on other sites More sharing options...

tonyman Posted July 25, 2013 Author Share Posted July 25, 2013 Levi , the 11th and 12th box from bottom I just cant get my head round .........7-9 =16 ? its not a plus ect ......and I know that's where I started going wrong Link to comment Share on other sites More sharing options...
dmjg Posted July 25, 2013 Share Posted July 25, 2013 Levi , the 11th and 12th box from bottom I just cant get my head round .........7-9 =16 ? its not a plus ect ......and I know that's where I started going wrong Remember you are working backwards Tonyman. The 7 -9 requires a +9 to give an answer of 16. When you then read the sum forwards it gives 16 - 9 = 7 Link to comment Share on other sites More sharing options...
Counting Stars Posted July 25, 2013 Share Posted July 25, 2013 I am actually rubbish at Maths lol glad you've had others to help though xx Link to comment Share on other sites More sharing options...
Levi Posted July 25, 2013 Share Posted July 25, 2013 Christ tonyman, you made me panic there for a moment. I was quite sure I nailed this one, but then scrolled down and saw dmjg's comment. Yes, you have to think of it like this: "What minus 9 equals 7?" Or any other number and operation between. When will I be there.. good question, I will be shootin' up some IELTS examiner ass and when I am done with that then perhaps we'll get some decent speed on this migration thing. Or, I will get there sooner with a working holiday visa - but I still haven't read about it on immi site. Link to comment Share on other sites More sharing options...

These are basic skills. +, -, x , / (no proper division sign on iPad) The work is also highlighting problem solving skills. People are getting confused. How could this sheet be re written to make it less confusing? Maybe if that problem is sorted first, the whole task may become extremely easy. Going a bit deeper, all questions are linked. Kind of like life. All answers we generate now will influence answers we give in the future. I agree about the lack of times tables knowledge. But parents and governments demand primary schools have a varied curriculum. That leaves less time for basic Maths and English. After all, we need to learn Chinese or other languages before we become proficient in English, don't we???:arghh: Link to comment Share on other sites More sharing options...

I'd never get a job if i had to do this test, never got past GCSE maths but forgotten most of that now apart from the basics.

I was actually wondering if this was trying to introduce some of the skills of algebra without the scary x. After all, the last box are just a silly way of representing something like: x/2=7 (again no division sign) and so on. Personally, I find "reversing" more confusing than solving for x but that's just the way I was taught. In any case, I can see far more real world applications for a bit of algebra than a long series of boxes. Believe it or not, I still use algebra in my daily work at age 60!
