Assume that "P" and "Q" are logic propositions. I want to say "Since Q is true, so P is true". I want to say this, like one of the two sentences below. Which one is true (better)?

  • P follows by Q.

  • P follows from Q.

Thank you.

B follows from A

means that B can be derived logically from A.

"Follows from" is idiomatic.
