When someone says to tune to a -10 or +10 what does that mean. Probably a dumb question but I don't know the answer.

Cents are a measurement of pitch. There are 100 cents between each of the 12 notes of the equally tempered scale (C, C#, D, D#, E, etc.). An octave is 1200 cents.
Most electronic tuners use the cents scale, with 0 being the equally tempered (ET) tuning. -10 cents means 10/100 of a semitone flat of ET. +10 cents means 10/100 of a semitone sharp of ET.

And according to research, there are 4 Cent's per Hz...So 438 Hz is about 8 cents flat of 440 Hz.

That is only true in the neighborhood of 440 Hz. Hz is a linear scale, and cents is a logarithmic scale. For comparison, 218 Hz is 16 cents flat of 220 Hz, and 878 cents is 4 cents flat of 880 Hz. Math can be confusing.
We use the "4 cents per Hz" ratio to calculate cents on electronic tuners that only have a 440 Hz calibration scale on them. It works.
