Answer 5

\(^5 P _5 = 120\), aka \(5!\)

poor Sheryl.

Answer 6

@Layla you only included 4 people in your answer when there are five in the problem

Also, I said 5! Which is not the same as 5 (as sillybilly stated, 5! = 120)

Answer 7

@Vocaloid Okay people make mistakes

Answer 8

Mistakes should be calmly pointed out and corrected

If I make a math mistake I would like someone to point it out so I don't mislead people
