You have four, fours.

4, 4, 4, 4.

You need to use all fours to create the numbers one to twenty, for example:

1 = 4+4 / 4+4


You can use:

+ - / * . √

Plus, Minus, Divide, Times by, decimal points, Square roots, to create the numbers.


I've only got a few so far. :P

I got everything except 19

The answer is the reciprocal of .

Do your own homework lazy pantsbum.

I refuse to do this.

Its not homework.

Post them then :P


I've about 3/4 of them atm.

Don't do this, Luciene...

I have all of them.
1=4.4/4.4
2=2+2*.4+.4
3=4+4+4/4
4=4+4/4+2
5=4/4+2+2
6=4+4/4+4
7=4/4+4+2
8=2+2+2+2
9=44/4-2
10=2+2+2+4
11=2/.4+4+2
12=4+4+2+2
13=44/4+2
14=4+4+4+2
15=2+2+2/.4
16=4+4+4+4
17=2+4/.4+2
18=2+2*4+2
19=2+4/.4+4
20=4+4+2*2

I used 2 for the square root of four.

Wow, why didn't I think of 44...... :unsure:

Well, I did get to 5 before thinking 'WTF am I doing?'

I didn't do them in order, I just randomly got numbers.

I did 1-6, got bored, and left the computer.

i didnt even start...i cant do maths to save my life

i have a good maths problem...


How can you make all the numbers up to 27 using only 4 whole numbers. You can plus, minus, times and divide them. Each number can only beused for each eqaution. There is no need to do anything fancy with the numbers, like squaring them.

I probably won't even start this, but can use you the negative version of the number?

...that's just subtracting it.

unless your multiplying/dividing....

there is no need to use negitaive numbers, i don't even know if it would work then.
