Mental math ×3

Mental math ×3 means solving three quick calculations without a calculator, in about 30 seconds. The app checks your answers, so your brain has to switch on before the feed does.

How to do it

Mental math ×3, step by step.

  1. Read the calculation.

  2. Solve it in your head, no calculator, and type the answer.

  3. Repeat for three calculations: the app checks each answer.

Why this Move

Why it's a good Move before a scroll.

  • Switches your brain out of autopilot

  • Checked answers: no fooling yourself

  • Invisible: part of discreet mode

Stop if anything hurts, and swap the Move with “I can't do this” in the app. MiniMove is a wellbeing app, not medical advice.

Questions

About Mental math ×3

How long does it take?

About 30 seconds, start to finish. Every Move in MiniMove takes 90 seconds or less.

What if I can't do it?

Take your time and count on your fingers if you like: nobody is grading you. “I can't do this” in the app swaps in another Move and stops suggesting it.

How many minutes does it unlock?

Whatever the Move, it opens the app for the window you chose: 5, 15, 30 or 60 minutes of real use (15 by default), capped at twice that on the clock. It also goes into your Bank.
