Don't simply "learn math" or chemistry or physics or whatever.
Pick up some interest or hobby you might like (and you both could share)
For example- astronomy
In process of learning about it you will learn related physics (about inertia, radiation, gravity, etc.), chemistry (composition of solar system, matter state, molecules and their combinations, etc.) and math (formulas of what is going on)
If you step one step further and try to build your own telescope you will again meet physics (lenses and light), chemistry (actual materials used for telescope) and math (calculating everything)
And when your telescope will be ready you will be forced to learn reading starmaps (or moonmap if you prefer observing moon)
And after all this you might ask you girl out on stargazing picnic (with romantic music for additional effect)
Just a thought
