Best apps for mental maths???

Justin asked on Jul 07, 2019 - 2 answers

Hello all,

I am interested to see if anyone is using any apps on their phone to practice mental maths whilst away from the desk.

I have been using "Cool Maths Games" on android. It gives you the option of have the problem presented either visually or via audio and you can answer either via the keypad, multiple choice or by voice.

Please let me know if anyone has any other good recommendations

You can use preplounge tool, Viktor Cheng tool, Mimir Math on iOS

Also, I recommend practicing the following:

  • Learn how to multiply double digit numbers (
  • Learn the division table up to 1/11 (i.e. 5/6 = 83.3)
  • Learn how to work with zeros using powers (E.g: 4000000 = 4*10ˆ6)

Good luck with your interviews!

I found Victor Cheng's Math Tool pretty interesting and beneficial:
