Base damage of weakness and resistance?

[famicomman]

Okay, while most of my cards (from currents sets) have + so much or -so much, what is the damage on those that just have the energy symbol on them? Thanks for your help everyone.

 

[PokePockets]

on the Pre DP cards. The Resistance of the Pokemon is -30 and Weakness is Double Damage.
