help me as my brain has gone to mush...
helping out at school today we were doing a maths game - its like the numbers game on Countdown.
You have 4 numbers and you have to use + - x / to get the answer 24
eg 6 4 7 7 you can say 6x4 = 24, and 1/1=1 and 24x1=24
now, we got the numbers 9 8 8 & 4 and I can't work out how to get 24
over to you brainboxes....
Is this your homework?
I don't think you are allowed to ask other people for the answer to your homework.
9-8 = 1
4-1 = 3
3 x 8 = 24
Is that what you mean?
This ones a bit harder.
A cow is tied to the fence of a perfectly circular grass covered field. How long would the rope have to be for the cow to eat exactly half the area of the field?
9-4 = 5
8-5 = 3
8*3 = 24
or all in one line (8 - (9-4))*8
9 x 4 = 36; 8+8=16 -4 =12 --------- 36-12=24
Tut tut, online plagerism....
No you have to use all of the numbers
this isn't my homework, but it's annoying me that I couldn't work it out
JB - isn't that a how long is a piece of string type question
use all the numbers once
(and htese 11 yr olds aren't clever enough to use brackets yet!)
Aha - get you point Mouse! yes that would work wouldn't it
vitual choccy on it's way to you
Sharpen the cows teeth, put some grass on the rope, allow the cow to munch through the rope and then leave it aforementioned field to eat the grass.
Does that get past the no thumb problem?
Closest I've managed so far is 28.
