First Conditional

Watch the video (If you haven't seen one about zero conditional watch that first http://telegra.ph/Zero-Conditional-10-12)

1. Do you understand what a first conditionl sentence is?
2. What is the difference between first and zero conditionals?
3. What do they have in common.

And again the sentence to translate.

Если ты не придёшь, я тоже не приду!
