New to forex have question

what does it mean to go long or to get short on a trade?

this is from babypips pre-school lesson:

Long/Short
First, you should determine whether you want to buy or sell.

If you want to buy (which actually means buy the base currency and sell the quote currency), you want the base currency to rise in value and then you would sell it back at a higher price. In trader’s talk, this is called “going long” or taking a “long position”. [B]Just remember: long = buy [/B]

If you want to sell (which actually means sell the base currency and buy the quote currency), you want the base currency to fall in value and then you would buy it back at a lower price. This is called “going short” or taking a “short position”. [B]Short = sell[/B].
