anyone good at maths
 

my daughter has brought home some maths homework & it has beaten me need help

homework was to work out 1 - 30 only using numbers 1,2,3,& 4 done all except no 29 any ideas will be much appeachiated cause i said it can,t be done.

you can only add,subbtract or multiply

eg 2+3 x 4 = 20 ect

thanks

Can you use the numbers 1, 2, 3 & 4 only once each?

Or is (2+3) x (4+2) -1 acceptable?

1+1+1+1+1....you get the picture

only once
lol

You can also use divide - i've tried on and off all day to solve it, no luck yet! And this is a nine year olds homework!

The most I can make is 26...isn't 29 one of those numberse that can only be divided by 29 and 1? Therefore it has no multiples so it can't be done given that you don't have enough numbers to do it by adding

prime number

That's the one, I knew it wasn't a square number but the other one...couldn't remember what "other one" was lol

it dead easy if you can square the numbers...

Even easier if you can cube them

3 cubed plus 2... brilliant... lol

(4-1)³+2


:shrug: I´m overchallenged

sorry you ca'nt square numbers or cube them. Wish you could!

says who??? did it say you can't?? course not

cant help,sorry but how hard for a nine year old

Could it be that 29 doesn't have a solution using only the numbers 1, 2, 3 & 4? I've asked some of the maths gurus here at work (these are people who talk in numbers not English) and they can't come up with a solution.

I have maths next so I'll ask my higher maths teacher :-) if it is possible to create 29 out of numbers using them once.

She'll be able to work it out I'm sure or give us clues ot something....
WIll let you know if I get anything... Hope this helps

Can just imagine the kid going into school..

"Your parents help with this?"

"No miss"

"Anyone help you with this?"

"No miss"

"So how come MLUKFC has fallen twenty places in the website inteligence ratings?"

"Don't know miss"

Andy's answer looks good to me?

7x4+1?

how do you make the 7

2+5?

and where do you get the 5 from

From my butt...I got it now...all simple numbers, oh well...today it's busy at work...

Can you do to the power?
