When something is easy to understand or do, it is straightforwards.
If something is straightforwards, it is usually good because it means it is not complicated.
Examples:
The instructions are straightforwards.
It's straightforwards to tie my shoes.
She finds the game straightforwards to play.
The question was so straightforwards that it made everyone laugh.
The path to the treasure was straightforwards, just follow the map and you'll find it easily.
The answer was so straightforwards that I will always remember it.
