More is Less, Less is More

When lecturer ask us to explain the meaning of More is Less, Less is More, my face expression shows =.='' ... Sweat ! totally stun, how come more is less, less is more. More means more/a lot of !Less means less/seldom ! How come this 2 can be combine together ?

After that i go wikipedia search it, here is the result:

Less is more:

That which is less complicated is often better understood and more appreciated than what is more complicated; simplicity is preferable to complexity' brevity in communication is more effective than verbosity.

By the ways, i cant find the meaning of more is less. But after i read this sentences, i start to understand the meaning of less is more,more is less. From my point of view, this is meaningful and useful for designer. Take a example,a poster that we wanna to design. Sometime we put a lot of picture, maybe it will looks nice and full of information, but then it also look messy and hard to focus the point. Something like a billboard that full contain but actually look at it, it just nothing. Nothing i can get in the billboard, everything i know in the billboard only but others side information.But a billboard just a shows a product picture,maybe audience will start question what is the product,how the product function, how much is it and so on , they will go find the information as well and this is what i trying to means less is more.

This the the funny sentences that come to my mind, confusing !

A simple design without text can be meaningful.

A simple design with text can be meaningful too.
