How to understand Old Pokemon card strength or weakness??

Question

I understand that newer pokemon cards show the amount of strength or weakness, but I found some older cards that only show the type. Is it -10 or something else?

Answer 1

Wel, most of the older card have only the picture under the weakness column.  That's mean any pokemon that type could hit double when it attack that pokemon.  I hope this should help you in play pokemon

Answer 2

In the older cards...the weakness id double the damage of the attack.....an ex. is if a Fire Pokemon uses Ember that normally takes away 20HP....on a Grass Pokemon...then it will take away 40HP☺☻

Answer 3

Weakness: Double the damage

Resistance: damage is reduced by 30

Answer 4

For older cards, weakness doubles the damage.
