2+ (2-2)x2 = 2

Yes. It's 22 x 2 ÷ 2

(2+2+2)=6 divided by the 4th 2 = 3

(2 + 2)*2/2 = 4

There are four 2s in a standard deck of playing cards.

There are four 2s in a deck of cards, one of each suit.

Yes: 2 x 2 x 2 + 2!

4!=4x3x2x1=24

4s2 - 9 can be expressed by using the identity: a2 - b2 = (a-b)(a+b) Therefore, 4s2 - 9 = (2s)2 - 32 = (2s-3)(2s+3)

Yyou could do (2x2)! (=24) then / 2 (= 12) then - 2/2 (= 11) (where ! means factorial, so 4! means 4x3x2x1, = 24) Is that allowed?

no.

Using four fours, you can get 19 with the following sum: 4! - 4 - (4 / 4) That is, four factorial minus four - (four divided by four) - 24 - 4 - (4 / 4) = 19

4! + (4 + 4!)/4 = 24 + (4 + 24)/4 = 24 + 28/4 = 24 + 7 = 31

[(4! + √4)/.4] + 4! = [(24 + 2)/.4] + 24 = 26/.4 + 24 = 65 + 24 = 89
