2 × 2 2 × 2 = 2 + 2 2 + 2 = 22 22 = 2 2 2 × 2 = 1 \Large\frac{2\times2}{2\times2}=\frac{2+2}{2+2}=\frac{22}{22}=\frac{2^2}{2\times2}=1

2 2 2 2 = ( 2 2 ) 22 = ( 2 2 ) 2 × 2 = ( 2 2 ) 2 + 2 = 1 \Large\frac22^{\frac22}=(\frac22)^{22}=(\frac22)^{2\times2}=(\frac22)^{2+2}=1

( 22 ! ) 2 − 2 = 2 ( 2 − 2 ) 2 = 1 \Large(22!)^{2-2}=2^{(2-2)^{2}}=1
