Yes
2+ (2-2)x2 = 2
Yes, you can make 11 using only four 2s by using the following mathematical expression: (2 + 2) x (2 + 2) = 4 x 4 = 16. Then, subtract (2/2) to get 16 - 1 = 15. Finally, take the square root of 15 to get √15 ≈ 3.87, which is close to 4. Therefore, using four 2s, you can approximate 11 by following these steps.
Yyou could do (2x2)! (=24) then / 2 (= 12) then - 2/2 (= 11) (where ! means factorial, so 4! means 4x3x2x1, = 24) Is that allowed?

Yes
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 deck of cards, one of each suit.

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)
no.
