no.
22 + 22 - 2 = 42
Yes
22/2 - 2
(22/2+2)x2
2+ (2-2)x2 = 2
3 x (22)2 + 2 = 50
(2+2+2)=6 divided by the 4th 2 = 3
22+22
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.
(2*2)! * 2/2 = 4! * 1 = 24 * 1 = 24
(2 + 2)*2/2 = 4
