Thank of it this way:
2 > 1 : this means that this little Pac-Man want to eat the bigger number so it would be the same if you have
1 < 2 : here 2 it's still greater then 1
1/2 = 0.5 : here we don't have a pacman but you know that 1/2 It's actually 0.5
So now if you have:
2n > -4 [divide by 2]
n > -2
And if you have a (image) Then this means that x is greater that -2 but it's less than 1, so x would be between -2 and 1
Hope this helps, ask any questions if you have.
