i have a question about animate dead 3.5

i don't really under how many undead can i summon with this spell animate dead please explain so a noob like me can understand cause the handbook(below) way of saying make my brain hurt The undead you create remain under your control indefinitely. No matter how many times you use this spell, however, you can control only 4 HD worth of undead creatures per caster level . If you exceed this number, all the newly created creatures fall under your control, and any excess undead from previous castings become uncontrolled. (You choose which creatures are released.) If you are a cleric , any undead you might command by virtue of your power to command or rebuke undead do not count toward the limit.

Technically, this isn't the kind of question that these forums are for. Someone will pop on and give you a link to <a href="http://reddit.com/r/rpg" rel="nofollow">http://reddit.com/r/rpg</a> or some such. As for your question, I don't think this passage describes how many you summon, it only describes how many you can control. Assuming you have a 10th level cleric, and you can control 4 hit dice of undead per caster level, you could control 40 hit dice of undead. If skeletons are 1/2 hit dice, you could control 80 of them. If wights are 4 hit dice, you could control 20 of them. Et cetra. Look further up the spell and it should give you some idea of how many you can summon. The text implies it is less than they number you can control.
