How to improve mental agility with number practice
If you are wondering how to improve mental agility when working with numbers, start with a few calculations you can understand and check. Knowing useful number facts gives you more ways to approach a puzzle. This guide focuses on maths practice, rather than making claims about memory or health.
Build on familiar times tables
Start with the tables you know. Then try 13, 25, 75 or 125. You can work out a less familiar table from simpler facts instead of learning every answer in isolation.
For example, 25 is a quarter of 100. To calculate 12 × 25, find 12 × 100 = 1,200, then divide by four. The answer is 300.
Likewise, 125 is an eighth of 1,000. So 8 × 125 = 1,000 and 16 × 125 = 2,000. The first eight multiples are 125, 250, 375, 500, 625, 750, 875 and 1,000.

How to improve mental agility: try another method
When a calculation looks awkward, break it into parts. For example, to work out 22 × 16, split 16 into 10 + 5 + 1:
- 22 × 10 = 220
- 22 × 5 = 110
- 22 × 1 = 22
- 220 + 110 + 22 = 352
You could also double 22 four times: 44, 88, 176, 352. Both methods give the same answer. Comparing them helps you find an approach that feels manageable.
Connect fractions and decimals
Keep a few familiar equivalents in mind: 1/2 = 0.5, 1/4 = 0.25 and 1/5 = 0.2. Some decimals continue without ending. For example, 1/3 = 0.333… and 1/6 = 0.1666… . The dots matter: these are not exact three-place decimals.
Try using those facts in a practical question. A quarter of $80 is $20. That also tells you that a 25% discount on $80 is $20, leaving $60 to pay.
Practise without rushing
Choose a few questions, explain your steps and check the results. If a method is confusing, use smaller numbers first. Our mental maths tips with worked examples offer more starting points.
