  -[(1 X 2) -(3 X 4)]^2

  - [2 - 12]^2

  -[-10^2]=-100

 

12 + 3/4=12.75

[(3x4)-(1x2)]2

Hi Guest,    You used the 2 twice in both you answers.     frown

 

 

I can 'fudge' too.   LOL

 

using 1,2,3,4 only once {operations (PEMDAS) and factorials allowed} how do you get -100 and 12.75?

 

1)        (2+3)1 / 4   =   51  /  4   =   12.75       LOL    cheeky

 

Here is another 'fudge' one

 

2)         (12)+3/4      = 12  3/4

 

HERE IS A REAL ONE!!

 

3)      (3!+4)^2  =100      If I haver to use the 1 as well I can just multiply the whole lot by 1.   cheekylaughwink
