The IELTS Speaking test often includes questions about everyday experiences, including situations that require mental calculations. One such topic that has appeared in past exams and may continue to be relevant is describing a time when you performed a lengthy calculation without using a calculator. This subject allows examiners to assess your ability to recount a specific event, explain a process, and discuss problem-solving skills.

Describe an online shopping experience you had can be another interesting topic that may come up in your IELTS Speaking test. However, let’s focus on how to effectively answer questions about mental calculations.

Part 1: Introduction and Interview

In this section, the examiner might ask general questions about math and calculations. Here’s an example question with a suggested answer:

Q: How often do you do calculations in your daily life?

A: I find myself doing mental calculations quite frequently in my day-to-day life. Whether it’s figuring out discounts while shopping, splitting bills at restaurants, or estimating travel times, I often rely on my mental math skills. It’s become second nature to me, and I find it both practical and mentally stimulating.

Part 2: Long Turn

Here’s a sample cue card related to the topic:

Describe A Time When You Did A Lengthy Calculation Without Using A Calculator
You should say:

• What the calculation was about
• Why you had to do it without a calculator
• How you managed to do it
• And explain how you felt about doing this calculation

Sample Answer (Band 6-7):

I remember a time when I had to do a complex calculation without a calculator. It was during a power outage at my university, and we were in the middle of a statistics exam. The calculation involved finding the standard deviation of a large dataset.

Since we couldn’t use our calculators, we had to rely on our mental math skills and paper-and-pencil methods. It was challenging because the numbers were quite large, and there were many steps involved.

To manage this, I broke down the calculation into smaller, manageable parts. I started by calculating the mean, then worked on the differences from the mean, and finally computed the variance and standard deviation. It took me a while, but I methodically worked through each step.

Honestly, I felt quite anxious at first, but as I progressed, I began to feel a sense of accomplishment. It was a test of my mathematical abilities and problem-solving skills. In the end, I felt proud that I could complete such a complex task without relying on technology.

Sample Answer (Band 8-9):

I vividly recall an instance where I had to perform an intricate calculation sans calculator during a critical juncture in my academic career. It was amidst my final year econometrics exam, and we were tasked with computing a multiple regression analysis by hand.

The absence of calculators was intentional, designed to test our fundamental understanding of the statistical concepts and our ability to manipulate complex mathematical equations mentally. The calculation involved determining coefficients, standard errors, and the coefficient of determination for a model with multiple independent variables.

To tackle this Herculean task, I employed a systematic approach. I began by organizing the data into a structured format, then proceeded to calculate the means and deviations. Subsequently, I meticulously worked through the matrix algebra, using shortcuts and estimation techniques to simplify the process. I relied heavily on my knowledge of number properties and algebraic identities to expedite the calculations.

Initially, I felt a surge of adrenaline mixed with trepidation. However, as I delved deeper into the problem, a sense of intellectual excitement took over. It was an exhilarating challenge that pushed the boundaries of my mathematical prowess. Successfully completing the calculation left me with an overwhelming sense of accomplishment and reinforced my confidence in my analytical abilities. This experience was a testament to the power of mental agility and the importance of mastering fundamental concepts in our increasingly technology-dependent world.

Follow-up Questions:

1. How did you feel after completing the calculation?
2. Do you think it’s important for people to be able to do calculations without a calculator? Why or why not?

Sample Answers:

Band 6-7:

1. After finishing the calculation, I felt relieved and proud. It was a challenging task, but overcoming it gave me a sense of achievement.

2. Yes, I think it’s quite important. Being able to do mental math can be really useful in daily life, especially when you don’t have a calculator handy. It also helps in developing problem-solving skills.

Band 8-9:

1. Upon completing the calculation, I experienced a profound sense of accomplishment coupled with intellectual satisfaction. The process was mentally taxing yet incredibly rewarding, reaffirming my confidence in my analytical capabilities.

2. Absolutely, I believe it’s crucial for individuals to possess this skill. The ability to perform calculations without technological aids fosters critical thinking and enhances cognitive flexibility. Moreover, it cultivates a deeper understanding of mathematical concepts, which is invaluable in various professional fields and everyday problem-solving scenarios.

Part 3: Two-way Discussion

Q: In what situations do people need to do calculations in their heads?

A (Band 6-7): People often need to do mental calculations in everyday situations like shopping, cooking, or managing time. For example, when you’re buying groceries, you might need to quickly add up prices or calculate discounts. In cooking, you might need to adjust recipe quantities. It’s also useful for estimating travel times or splitting bills with friends.

A (Band 8-9): Mental calculations are ubiquitous in our daily lives, ranging from mundane tasks to more complex decision-making processes. In financial contexts, such as budgeting or investment planning, the ability to swiftly estimate percentages or compound interest can be crucial. Professionals in fields like engineering or architecture often need to perform quick dimensional calculations or estimate material requirements. Even in social situations, such as tipping at restaurants or dividing shared expenses, mental math skills prove invaluable. Moreover, in time-sensitive scenarios like emergency response or competitive sports, the capacity for rapid mental calculations can be literally life-saving or game-changing.

Q: Do you think calculators have made people worse at mental arithmetic?

A (Band 6-7): I think calculators have had both positive and negative effects. On one hand, they’ve made complex calculations easier and faster, which is great for many jobs and studies. But on the other hand, I believe people rely on them too much for simple calculations. This might have made some people less confident in their mental math skills. However, I don’t think calculators are entirely to blame – it’s also about how math is taught and practiced.

A (Band 8-9): The impact of calculators on mental arithmetic proficiency is a nuanced issue. While calculators have undeniably revolutionized our approach to complex mathematical operations, potentially diminishing the perceived necessity for mental math skills, I would argue that they haven’t inherently made people worse at arithmetic. Rather, they’ve shifted the focus of mathematical education and practice.

Calculators have liberated cognitive resources for higher-order problem-solving and conceptual understanding. However, this has come at the cost of regular practice in basic arithmetic, which is crucial for maintaining mental math agility. The key lies in striking a balance – leveraging technology for complex calculations while continuing to nurture fundamental mental math skills through deliberate practice and application in daily life.

Moreover, the ubiquity of calculators has paradoxically highlighted the value of quick mental calculations in scenarios where accessing a calculator is impractical or time-consuming. This realization has led to a renewed emphasis on mental math in many educational curricula, aiming to cultivate both technological proficiency and cognitive flexibility.
