using the digits 2,0,1,and 4 using any math operations how can you make the answers 10, 11, 13, 20

Question

You can use any math operations

Answer 1

All these answers are good, but I don't like their answers for 20. So I will offer this version.

4! - 2!- 1!- 0! =20

Answer 2

20 = 4/.2 + 1 - 0! 

 

13 = 4(2 + 1) + 0! 

 

11 = 4(2 + 1) - 0!

 

10 = 4(2) + 1 + 0!

Answer 3

Here are some other answers using each digit individually.

20=(2/.1)(4^0)

13=(4!)/2+1^0

11=(2/.1)/√4+0!

10=(2/.1)/√4+0

Answer 4

Dog(?):

 

10 = 20/2

 

11 = 20/2 + 1

 

13 = 20/2 + 4 - 1

 

20= (20/2) x 2

 

One of the many many possibilites.
