Times table gives wrong answers

When the narrator said that 3 x 8 = 25, along with another multiplication, I realised that I could not listen any further.

Marred by wrong information, 3 x 8 is 24, not 25

Incorrect information. As on 13th February 2018, through the times table the audio book narrates "times eight equals twenty four" during the three times table which is wrong. it should be 25 which is jarring. Also how does 6 × 8 = 38?
