Yes

22x2x2 is 88

Yes: 2 x 2 x 2 + 2!

2+ (2-2)x2 = 2

22/2 - 2

Four 2s make 8, so 25% is your answer

2 + 2 + 2 + 2 = 8

Yes. It's 22 x 2 ÷ 2

22 + 22 - 2 = 42

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

(2*2)! * 2/2 = 4! * 1 = 24 * 1 = 24

(2 + 2)*2/2 = 4

2s,6p,

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

Yes

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.

no.

3 x (22)2 + 2 = 50

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)

2s-4 equals 2(s-2). You can find the answer by factoring two out of both numbers.

no, with 5 yes, 2x2x2-2/2 actually it depends on whether you accept differentiation in this. if yes, i can make it. 2+2+2+((d/dx)2)! =6+(0)! =7

Up to 4p, the energy levels go as follows: 1s 2s 2p 3s 3p 4s 3d 4p

All numbers in the 2s column on the multiplication table end in the even numbers 2, 4, 6, 8, or 0.
