Introduction
Just a few years ago, students needed to remember multiplication tables and perform calculations manually. Today, a child can ask an AI tool a maths question and receive an answer within seconds. Smartphones, calculators, and artificial intelligence have transformed the way we access information.
This technological revolution has led many parents to ask an important question:
If AI and calculators can solve maths problems instantly, does my child still need mental maths?
The answer is a resounding yes.
In fact, mental maths may be more important today than at any other time in history. While technology can provide answers, it cannot replace a child’s ability to think critically, estimate, analyze information, and solve problems independently.
Mental maths is not simply about calculating quickly. It is about developing the brain’s ability to understand numbers, recognize patterns, make logical decisions, and approach challenges with confidence.
As the world moves deeper into the AI age, children who develop strong mental mathematics skills will be better equipped to succeed in school, future careers, and everyday life.
The Rise of Artificial Intelligence in Education
Artificial intelligence is rapidly changing education around the world.
Students can now:
- Use AI-powered tutoring systems
- Generate homework explanations
- Solve equations instantly
- Access personalized learning support
- Receive immediate feedback
These innovations offer many benefits. However, they also create a new challenge.
When technology does most of the thinking, children may become passive learners rather than active thinkers.
A calculator can tell a child that:
48 × 25 = 1200
But can the child recognize whether the answer is reasonable?
Can the child estimate the result before entering it into a calculator?
Can the child understand why the answer is 1200?
These questions reveal the difference between obtaining an answer and truly understanding mathematics.
What Is Mental Maths?
Mental maths refers to performing calculations in the mind without relying on paper, calculators, or digital tools.
Mental arithmetic practice helps children develop strategies such as:
- Breaking numbers into smaller parts
- Estimating answers
- Recognizing numerical patterns
- Using number relationships
- Applying logical reasoning
For example:
Instead of calculating:
19 × 5
using a calculator, a student might think:
20 × 5 = 100
100 − 5 = 95
This flexible approach develops mathematical thinking that extends far beyond simple calculations.
Mental Maths Builds the Foundation of Number Sense
One of the most important benefits of mental mathematics is the development of number sense.
Number sense is the ability to understand:
- How numbers relate to one another
- Magnitude and size
- Patterns and relationships
- Estimation techniques
- Efficient calculation methods
Children with strong number sense can quickly recognize mistakes.
For example:
If a calculator accidentally displays:
48 × 25 = 12000
A child with strong number sense immediately realizes something is wrong.
Without number sense, students often accept calculator answers without question.
In the AI age, this skill becomes increasingly valuable.
Why Mental Maths Matters More Than Ever in 2026
Many parents assume technology has reduced the need for mental calculation practice.
The opposite is true.
Technology increases the need for critical thinking because information is now available instantly.
Children must learn how to:
- Evaluate information
- Detect errors
- Interpret results
- Make decisions
Mental maths trains the brain to perform these tasks.
It teaches children to think rather than simply receive answers.
AI Can Calculate Faster Than Humans
No human can compete with AI in raw calculation speed.
Artificial intelligence can solve thousands of equations in seconds.
Therefore, the goal of mental maths is not to beat AI at arithmetic.
The goal is to develop abilities that AI cannot replace.
These include:
Reasoning
Understanding why an answer is correct.
Judgment
Determining whether an answer makes sense.
Creativity
Finding multiple ways to solve a problem.
Adaptability
Applying knowledge in unfamiliar situations.
These skills are becoming increasingly important in modern education and future careers.
The Hidden Connection Between Mental Maths and Problem-Solving
When children practice mental maths regularly, they learn to approach challenges strategically.
Consider this question:
25% of 240
Many students reach for a calculator.
A mentally trained student may think:
25% = one quarter
240 ÷ 4 = 60
Answer = 60
This approach demonstrates:
- Pattern recognition
- Flexible thinking
- Efficient reasoning
These are the same skills used in advanced problem-solving.
Mental Maths Strengthens Working Memory
Working memory is the brain’s ability to hold and manipulate information temporarily.
Children use working memory when:
- Following instructions
- Solving multi-step problems
- Reading comprehension passages
- Learning new concepts
Mental arithmetic practice exercises working memory daily.
As a result, students often experience improvements in concentration and academic performance.
Why Top Students Continue to Practice Mental Maths
Many high-achieving students already have access to calculators and advanced technology.
Yet they continue practicing mental maths.
Why?
Because they understand that strong thinking skills create a competitive advantage.
Mental maths helps students:
- Complete exams faster
- Reduce careless mistakes
- Improve confidence
- Solve problems efficiently
- Understand advanced mathematical concepts
Success is not determined by the tools available but by the ability to use those tools intelligently.
Future Careers Require Human Thinking
Many careers of the future will involve:
- Artificial Intelligence
- Robotics
- Data Science
- Software Development
- Engineering
- Finance
- Cybersecurity
These professions require individuals who can:
- Analyze information
- Identify patterns
- Solve complex problems
- Make logical decisions
Mental maths develops these abilities from an early age.
Children who practice mental calculation regularly build cognitive skills that support long-term success.
How Parents Can Encourage Mental Maths at Home
Mental maths practice does not require expensive resources.
Parents can encourage learning through daily activities.
Examples include:
During Shopping
Ask:
“If an item costs $40 and has a 25% discount, how much will we save?”
During Travel
Ask:
“If we travel at 60 kilometres per hour, how long will it take to travel 120 kilometres?”
During Cooking
Ask:
“If a recipe serves 4 people, how much do we need for 8 people?”
These simple conversations develop mathematical thinking naturally.

Conclusion
Artificial intelligence and calculators are powerful tools, but they cannot replace human thinking.
The students who thrive in the future will not necessarily be those who have access to the best technology. Instead, they will be those who know how to think critically, solve problems creatively, and understand numbers deeply.
Mental maths develops exactly these skills.
In the AI age, mental maths is no longer just about faster calculations. It is about preparing children for a future where reasoning, adaptability, and problem-solving will matter more than ever.
Rather than competing with AI, children should learn the skills that AI cannot replace. Mental mathematics provides one of the strongest foundations for that journey.
