What Does Simultaneous Mean?

"Observer A" is on the x axis at position 0 and "observer B" is on the x axis at position x = 10. At t = 0 both set off flashbulbs. "Observer A" will see his flash immediately but will not see "observer B's" flash until the light has had time to reach him. So the two events are not simultaneous Or "Observer A" knows what the speed of light is and can calculate the actual time that event B occurred and he will determine that the time was t = 0 and he will therefore conclude that the two events were simultaneous.
