4

1+2 = 4

2-1 = 4

3/2 = 4

4*0 = 4

1/4 = 4

1-3 = 4

2*2 = 4

2-4 = 4

3*1+1-2 = 4

1+2+3 = 4

1-2 =  4

4-1+0 = 4

3*2 = 4

1+1= 4

3-4 = 4

and the permutation and combination goes on and on

Confused ? This is what people have in their mind when you say just 4(and nothing more)

PS : 4 was just a random number chosen. No offence against other numbers ;)

Box

All along

thoughts

that circled around

were

out-of-the-box

now I try to

 invent them

within

the boundary line

yet

I am still unaware

which is difficult -

to let it 

hang outside 

or make them

 confined
