FAQ Math 24

1. What Is Data in Maths?

Data in math refers to information, often numerical, that is collected for analysis and used to draw conclusions.

• Example: A list of test scores, temperatures recorded over a week, or population counts are all examples of data.

2. What Is Discriminant in Maths?

The discriminant is part of the quadratic formula, used to determine the nature of the roots of a quadratic equation $ax^2 + bx + c = 0$ . It is given by $\Delta = b^2 – 4ac$ .

• Example: If $\Delta > 0$ , the equation has two real roots; if $\Delta = 0$ , it has one real root; and if $\Delta < 0$ , it has two complex roots.

3. What Is $i^2$ in Math?

In math, $i$ is the imaginary unit, and $i^2 = -1$ .

• Example: $i^2 = -1$ .

4. What Is $i^3$  in Math?

$i^3$  in math is the cube of the imaginary unit $i$. Since $i^2 = -1$ , $i^3 = i^2 \times i = -i$ .

• Example: $i^3 = -i$ .

5. What Is Interest in Business Math?

Interest in business math refers to the cost of borrowing money or the profit earned on an investment. It can be calculated using simple or compound interest formulas.

• Simple Interest Formula: $$I = P \times r \times t$$ where $I$  is the interest, $P$  is the principal amount, $r$  is the interest rate, and $t$  is the time.

6. What Is Intersection Set in Math?

The intersection of two sets is the set of elements that are common to both sets. It is denoted by $A \cap B$ .

• Example: If $A = \{1, 2, 3\}$  and $B = \{2, 3, 4\}$ , then $A \cap B = \{2, 3\}$ .

7. What Is Jottings in Maths?

Jottings in math refers to quick, informal notes or workings out that help a student process a problem, especially in mental math or simple calculations.

8. What Is Line in Maths?

A line in math is a straight one-dimensional figure that extends infinitely in both directions. It has no thickness.

• Example: A line passing through points A and B is denoted as $\overleftrightarrow{AB}$ .

9. What Is MAD in Math?

MAD stands for Mean Absolute Deviation, which measures the average distance between each data point and the mean of the data set.

• Formula: $$MAD = \frac{\sum |x – \bar{x}|}{n}$$ where $x$ is each data point, $\bar{x}$  is the mean, and $n$ is the number of data points.

10. What Is Math 8?

Math 8 typically refers to a math curriculum taught in the 8th grade. It usually includes topics like algebra, geometry, and introductory data analysis.

11. What Is Math Used for in Everyday Life?

Math is used in everyday life for:

• Budgeting: Calculating expenses, savings, and interest.
• Cooking: Measuring ingredients and adjusting recipes.
• Shopping: Calculating discounts and taxes.
• Traveling: Estimating time, distance, and fuel costs.

12. What Is Mathes?

Mathes is not a standard term, but it could be an informal or colloquial abbreviation for mathematics.

13. What Is Number Name in Maths?

A number name is the written form of a number using words.

• Example: The number 123 is written as “one hundred twenty-three.”

14. What Is Octagon in Math?

An octagon is a polygon with eight sides and eight angles.

• Example: A regular octagon has equal sides and angles, each angle measuring 135°.

15. What Is Partitioning in Maths?

Partitioning refers to breaking down numbers into parts to simplify calculations. It’s commonly used in arithmetic and problem-solving.

• Example: Partitioning 78 as 70 + 8.

16. What Is Profit and Loss in Maths?

Profit is the amount earned after selling something for more than its cost. Loss occurs when the selling price is less than the cost price.

• Profit Formula: $$\text{Profit} = \text{Selling Price} – \text{Cost Price}$$ 
• Loss Formula: $$\text{Loss} = \text{Cost Price} – \text{Selling Price}$$ 

17. What Is $q$ in Math?

In math, $q$ is often used to represent a variable, but in some contexts, it can represent the quotient in division or be part of a sequence of terms in equations.

18. What Is Quadrilateral in Maths?

A quadrilateral is a four-sided polygon. There are various types, such as squares, rectangles, trapezoids, and rhombuses.

19. What Is RHS in Math?

RHS stands for the Right-Hand Side of an equation or expression. For example, in the equation $2x + 3 = 7$ , $7$ is the RHS.

20. What Is Soroban Math?

Soroban is the Japanese version of the abacus, a tool used for performing arithmetic operations like addition, subtraction, multiplication, and division.

21. What Is Statistics in Math?

Statistics is the branch of math that deals with collecting, analyzing, interpreting, and presenting data.

• Examples of statistics: Mean, median, mode, standard deviation, etc.

22. What Is Statistics Math with Examples?

Statistics involves analyzing data to extract useful information. Common examples include:

• Mean: The average value of a data set.
• Median: The middle value when data is arranged in order.
• Mode: The most frequent value in a data set.

23. What Is Subtraction in Math?

Subtraction is the mathematical operation of taking one quantity away from another.

• Example: $7 – 3 = 4$ .

24. What Is Ten Frames in Math?

A ten frame is a visual tool used to help children understand numbers, counting, and basic arithmetic. It consists of a 2×5 grid, where counters are placed to represent numbers up to 10.

25. What Is the Best Time to Study Maths?

The best time to study math varies by person, but many students find:

• Morning: Ideal for fresh focus and problem-solving.
• After Exercise: Mental clarity often improves after physical activity. The key is to choose a time when you are alert and free from distractions.

26. What Is the Definition of Term in Math?

A term in math refers to a single number, variable, or the product of numbers and variables in an algebraic expression.

• Example: In $5x + 3$ , both $5x$  and 3 are terms.

27. What Is the Full Form of Maths?

The full form of maths is mathematics.

28. What Is the Meaning of Division in Math?

Division is the operation of splitting a quantity into equal parts or groups. It is the inverse of multiplication.

• Example: $12 \div 4 = 3$ .

29. What Is the Meaning of Expression in Math?

An expression in math is a combination of numbers, variables, and operations (such as +, -, ×, ÷) without an equals sign.
