Our daily activities depend on mathematics. We employ mathematical ideas and principles in our everyday lives whether we are aware of it or not. Mental counting is one of the most crucial mathematical abilities you can master. The capacity to make mathematical calculations in your head without the aid of a calculator or any other external device is known as mental arithmetic. This piece will discuss the definition of mental arithmetic as well as its advantages, methods, and tools for developing your abilities.
Without the aid of a calculator, pen, or piece of paper, mental arithmetic is the process of conducting mathematical computations in your head. It entails using mental methods, like visualization, memorization, and pattern recognition to solve mathematical issues.
Finding out how to do mental math has many advantages. It can aid in your arithmetic ability development, which is one of the most important advantages. Your recall, focus, and problem-solving skills can all be enhanced by practicing mental math. Additionally, when you have to make fast calculations—for example, during tests, contests, or daily life—mental arithmetic can help you save time.
Many parents believe the earlier a child begins mental arithmetic, the faster they’ll master complex problems. However, this method works differently. Unlike learning a foreign language through games and dialogue, mental arithmetic begins with mastering the ancient abacus and then visualizing it.
The ideal age to start is five, as the brain is physiologically ready for such information at this stage. There’s no upper age limit, though. While ages 5–10 are considered optimal for achieving the best results, adults can also learn mental arithmetic successfully. It can even help them view situations from a different perspective.
Mental arithmetic is a system for performing quick calculations in your head. This method allows people to compute multi-digit numbers in a short time without pen or paper.
In traditional math, children begin with counting tangible objects: they use fingers, blocks, toy cars, or counting sticks. Once a child no longer needs to physically visualize three apples and two pears to understand that 3 + 2 equals 5, they transition to abstract concepts. At this stage, children rely on their understanding of numbers, applying logic and memory, as it’s not feasible to mentally picture 123 apples and 43 pears. Manipulating symbols becomes essential, and the larger the numbers, the more challenging it gets.
In mental arithmetic, there’s a helper tool—an abacus—that, unlike physical objects, can always be visualized. Initially, calculations are performed on the abacus. Over time, the physical abacus is replaced by an imagined one. Training begins with simple addition and subtraction, later progressing to multiplication, division, fractions, and roots.
Problem-solving methods differ too. Traditional math relies heavily on algorithms; a mistake in the sequence leads to incorrect results. Mental arithmetic, however, offers flexibility. Different approaches can be used to find the correct answer, encouraging creative thinking.
Moreover, mental arithmetic involves visualization and memory, which engages both hemispheres of the brain.
You can use a variety of methods to sharpen your mental math abilities. The most successful method is imagination. Visualization entails imagining figures and making computations in your head. Memorization is a different strategy that entails learning arithmetic tables, regular mathematical formulas, and other mathematical ideas by heart. Another efficient method for solving mathematical issues is pattern identification, which includes identifying patterns and connections between numbers.
An abacus (or soroban) is an ancient counting tool consisting of small movable beads arranged in columns on a frame. The beads are divided into "heavenly" (above the bar) and "earthly" (below the bar). The abacus, as it exists today, originated in ancient China.
To use the abacus, it must be "cleaned." This doesn’t mean dusting it but rather resetting it. Place the abacus at a palm’s distance from the table's edge. Stand it vertically to let the top beads touch the horizontal bar, then lay it flat again.
Each column has five beads: one heavenly bead (worth 5) and four earthly beads (worth 1 each). For example:
Always use your thumb to raise earthly beads and your index finger to lower them. For heavenly beads, use only the index finger. This consistent motion builds muscle memory, speeding up calculations.
Each column represents a digit place value. For instance:

Addition Example (22 + 15):
Subtraction Example (24 - 11):
For more complex calculations where there aren’t enough beads, additional steps are required. For example, to add 1 when no earthly beads remain, you can add a heavenly bead (5) and subtract 4.
To simplify this for children, mental arithmetic uses “helper” formulas, categorized as "younger friends" (numbers up to 5) and "older friends" (numbers up to 10). These formulas make addition and subtraction easier to grasp.
You can learn and practice mental math with the aid of a number of tools. The abacus, also known as a soroban, is a common instrument for performing calculations mentally. It is an ancient counting device used in Japan. You can also exercise mental arithmetic using a variety of applications and web tools, including worksheets, practice problems, and riddles. You can also engage in a number of competitions and courses to develop your abilities.

There are several measures you can take if you want to improve your brain computation abilities. Initially, begin by regularly performing mental math. Simple computations are a good place to start, and you can progress to more difficult issues over time. Second, employ problem-solving strategies like imagery, memory, and pattern recognition. Finally, use tools like courses, apps, and internet resources to help you exercise and develop your abilities.
Modern research has explored how mental arithmetic impacts cognitive function. In 2007, universities in the UK studied 3,185 children aged 7–11 in Sudan who regularly practiced abacus-based calculations. The experimental group scored 7 points higher on IQ tests compared to their peers who didn’t study mental arithmetic. Similarly, a 2008 study by Tsinghua University in China found that mental arithmetic training improved memory and attention in children.
