Very tricky maths problem for 10 year old?

82 replies

Dd, along with selected others of her class, has been given a maths problem which I can't work out and nor can dh:

Using numbers 2, 4, 6 and 8 and "divided by" and "equals", make every number from 1 to 32.
eg. 1 = 8 divided by 8; Can't use plus, minus or multiply. Can use each of the numbers as many times as necessary.

We can only get about 1/4 of the answers. Can anybody enlighten us and isn't this a bit tough for a 10year old or is this the way they teach maths these days?

Supposedly you can only use division, and you can only use the numbers as numbers, not as digits (so no 42/6 = 7).

As concluded eventually by everyone, if those really are the restrictions (as robinia's dd was positive they were) then it should not be possible to produce anything other than 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27 and 32.

So inquiring minds want to know what the teacher said!

SueW you look like you have a possible answer there.
May be a silly teacher

I have to admit I did my sink with Cillit Bang rather than as per Flylady, because I didn't have the stuff she specified and knew if I waited until I got it it'd be another couple of weeks of procrastination.

Good tip on the UK group -- I'll check that out.

Oh poo, posted on the wrong thread. But hey, at least it serves to bump this one up.

robinia, where are you? You've left us all on tenterhooks...
