1. What Is BODMAS in Maths?

BODMAS stands for Brackets, Orders (exponents, roots), Division, Multiplication, Addition, and Subtraction. It is the order of operations used to solve mathematical expressions.

• Example: In the expression $5 + 2 \times (3^2 – 1)$ , follow BODMAS to get the correct answer.

2. What Is a Consecutive Number in Math?

Consecutive numbers are numbers that follow one another in sequence without any gaps.

• Example: 3, 4, 5, and 6 are consecutive numbers.

3. What Is a Factor in Math?

A factor is a number that divides another number exactly, without leaving a remainder.

• Example: The factors of 12 are 1, 2, 3, 4, 6, and 12.

4. What Is a Figure in Math?

A figure in math is a shape or form, usually referring to geometric figures like squares, circles, triangles, etc.

5. What Is a Function in Math Domain and Range?

A function is a relationship between two sets where each input (domain) has exactly one output (range).

• Domain: The set of all possible inputs.
• Range: The set of all possible outputs.
• Example: For $f(x) = x^2$ , the domain is all real numbers, and the range is non-negative real numbers.

6. What Is a Function in Math Graph?

A function graph represents a function visually on a coordinate plane, where the x-axis represents the domain (input) and the y-axis represents the range (output).

• Example: The graph of $f(x) = x^2$  is a parabola.

7. What Is a Good Math SAT Score?

A good Math SAT score is typically considered to be 600-700. A score of 750 or higher is excellent, while a perfect score is 800.

8. What Is a Median in Math Geometry?

In geometry, a median is a line segment from a vertex of a triangle to the midpoint of the opposite side. It divides the triangle into two equal areas.

9. What Is a Plot in Math?

A plot is a graphical representation of data or a function on a coordinate plane. It shows the relationship between variables.

• Example: A scatter plot, line plot, or graph of a function.

10. What Is a Polygon in Math?

A polygon is a two-dimensional closed shape made up of straight lines.

• Example: Triangles, squares, and hexagons are all polygons.

11. What Is a Polyhedron in Math?

A polyhedron is a three-dimensional solid made up of flat polygonal faces.

• Example: A cube is a polyhedron with 6 square faces.

12. What Is a Quartile in Math?

A quartile divides a data set into four equal parts. The three quartiles are:

• Q1 (Lower Quartile): The value separating the lowest 25% of data.
• Q2 (Median): The middle value, separating the lower and upper halves.
• Q3 (Upper Quartile): The value separating the highest 25% of data.

13. What Is a Ray in Math?

A ray is a part of a line that starts at a specific point (the endpoint) and extends infinitely in one direction.

• Example: $\overrightarrow{AB}$  is a ray starting at point A and extending through point B.

14. What Is a Relation in Math Example?

A relation is a set of ordered pairs showing the relationship between elements of two sets.

• Example: $\{(1, 2), (2, 3), (3, 4)\}$  is a relation between two sets of numbers.

15. What Is a Rotation in Math?

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a specific angle.

• Example: Rotating a triangle by 90° around the origin.

16. What Is a T Chart in Math?

A T-chart is a type of table used to organize values of variables. It is often used to list input and output values for a function.

• Example:

  x	y = 2x
  1	2
  2	4
  3	6

17. What Is a Turning Point in Math?

A turning point is a point where a graph changes direction from increasing to decreasing or vice versa. It occurs at local maxima or minima of a function.

• Example: For $f(x) = x^2$, the turning point is at $(0, 0)$.

18. What Is a Well-Defined Set in Math?

A well-defined set is a set where it is clear whether an object belongs to the set or not. The rules for membership are unambiguous.

• Example: The set of all even numbers is well-defined.

19. What Is AAS in Math?

AAS stands for Angle-Angle-Side, a condition for triangle congruence. If two angles and a non-included side of one triangle are congruent to two angles and a corresponding side of another triangle, the triangles are congruent.

20. What Is Abacus Maths?

Abacus is a simple tool used to perform arithmetic calculations like addition, subtraction, multiplication, and division. It has been used for centuries as a counting aid.

21. What Is Abscissa in Math?

The abscissa is the x-coordinate of a point in a coordinate plane, representing the horizontal distance from the y-axis.

• Example: In the point $(3, 4)$ , the abscissa is 3.

22. What Is Addition in Math?

Addition is the mathematical operation of combining two or more numbers to get a sum.

• Example: $2 + 3 = 5$ .

23. What Is Additional Maths?

Additional Mathematics is an advanced math course that includes topics beyond the standard curriculum, such as calculus, advanced algebra, and trigonometry.

24. What Is an Algorithm in Math?

An algorithm is a step-by-step procedure for solving a problem or performing a calculation.

• Example: The long division algorithm for dividing numbers.

25. What Is an Inverse Function in Math?

The inverse function of $f(x)$  is a function that reverses the effect of $f(x)$ , denoted as $f^{-1}(x)$ . If $f(x)$ maps $x$ to $y$ , then $f^{-1}(y) = x$ .

• Example: If $f(x) = 2x + 3$ , then the inverse function $f^{-1}(x) = \frac{x – 3}{2}$.

26. What Is Average in Math?

Average (or mean) is the sum of all values divided by the number of values.

• Example: The average of 2, 3, and 4 is $\frac{2 + 3 + 4}{3} = 3$ .

27. What Is Capacity in Math?

Capacity refers to the amount that a container can hold, usually measured in liters, gallons, or cubic units.

28. What Is Conditional Probability in Math?

Conditional probability is the probability of an event occurring given that another event has already occurred.

• Formula: $$P(A|B) = \frac{P(A \cap B)}{P(B)}$$  where $P(A|B)$  is the probability of event $A$  happening given $B$  has occurred.

29. What Is Consecutive Integers in Math?

Consecutive integers are integers that follow each other in order, without gaps.

• Example: 5, 6, 7 are consecutive integers.

30. What Is Continuous in Math?

A function is continuous if there are no breaks, jumps, or gaps in its graph, meaning the function can be drawn without lifting the pen from the paper.

• Example: The function $f(x) = x^2$  is continuous for all real numbers.
