Yes
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)x2 = 2
22/2 - 2
22 + 22 - 2 = 42
Yes
22x2x2 is 88

2+ (2-2)x2 = 2
Yes. It's 22 x 2 ÷ 2
22/2 - 2
Four 2s make 8, so 25% is your answer
(2+2+2)=6 divided by the 4th 2 = 3
22 + 22 - 2 = 42
(2*2)! * 2/2 = 4! * 1 = 24 * 1 = 24
(2 + 2)*2/2 = 4
Using 4 bits the signed range of numbers is -8 to 7. When working with signed numbers one bit is the sign bit, thus with 4 bits this leaves 3 bits for the value. With 3 bits there are 8 possible values, which when using 2s complement have ranges: for non-negative numbers these are 0 to 7; for negative numbers these are -1 to -8. Thus the range for signed 4 bit numbers is -8 to 7.
