'SFML sf::Transform .translate ignores minus in float variable

I am making a game with a moving camera and I adjust every object drawn using the sf::Transform function and apply it to every draw call.

sf::Transform transform;

transform.translate(-camera.getX(), -camera.getY());

Camera.x is -450.0 and Camera.y is -263.0 and both are stored as floats.

If I run removing the minus before the coordinates in the translate function call it puts the camera at +450.0 and +263.0 rather than -450.0 and -263.0

sf::Transform transform; transform.translate(camera.getX(), camera.getY());

I am confused as to why I need to double up the minuses with both the object variable and the translate function call.

Thanks
