a² + b² = c².

Question: How do you solve linear equations?

Answer: To solve linear equations, you need to isolate the variable on one side by performing operations like addition, subtraction, multiplication, or division.

Question: What is a polynomial?

Answer: A polynomial is an expression made up of variables and constants combined using addition, subtraction, and multiplication.
For example, 2x² + 3x + 5 is a polynomial.

Question: How do you simplify an algebraic expression?

Answer: To simplify an algebraic expression, combine like terms and perform the operations according to the order of operations (PEMDAS).

Question: What is the difference between a rational number and an irrational number?

Answer: A rational number can be expressed as a fraction of two integers, while an irrational number cannot be written as a simple fraction.
For example, 1/2 is rational, but √2 is irrational.

Question: How do you find the LCM of two numbers?

Answer: To find the least common multiple (LCM) of two numbers, list their multiples and choose the smallest common multiple.
Alternatively, use the prime factorization method.

Question: How do you find the HCF of two numbers?

Answer: To find the highest common factor (HCF), list the factors of both numbers and find the largest factor they share.

Question: What is a quadratic equation?

Answer: A quadratic equation is an equation that can be written in the form ax² + bx + c = 0, where a, b, and c are constants and x is the variable.

Question: How do you solve a quadratic equation by factoring?

Answer: To solve a quadratic equation by factoring, rewrite the equation as a product of two binomials and set each factor equal to zero.

Question: What is the formula for the area of a circle?

Answer: The area of a circle is calculated using the formula:
Area = π × radius².

Question: How do you find the perimeter of a rectangle?

Answer: The perimeter of a rectangle is calculated by adding the lengths of all four sides:
Perimeter = 2 × (length + width).

Question: What is a coordinate plane?

Answer: A coordinate plane is a two-dimensional surface where points are plotted using pairs of numbers (x, y) to represent their position.

Question: How do you plot a point on the coordinate plane?

Answer: To plot a point, start at the origin (0, 0), move horizontally along the x-axis, then move vertically along the y-axis to reach the point.

Question: What is a ratio?

Answer: A ratio is a relationship between two numbers that shows how many times the first number contains the second.
For example, the ratio of 2 to 3 is written as 2:3.

Question: How do you solve a proportion?

Answer: To solve a proportion, cross-multiply and then divide to find the unknown value.

Question: What is a surface area of a cuboid?

Answer: The surface area of a cuboid is the sum of the areas of all six rectangular faces.
It is calculated using the formula:
Surface Area = 2(lw + lh + wh).

Question: What is a probability?

Answer: Probability is the measure of how likely an event is to happen.
It is calculated as the ratio of favorable outcomes to total outcomes.

Question: How do you find the volume of a cube?

Answer: The volume of a cube is found using the formula:
Volume = side³, where "side" is the length of any edge of the cube.

Question: What is the distributive property in mathematics?

Answer: The distributive property states that multiplying a number by the sum of two numbers is the same as multiplying the number by each number and then adding the results.
For example, a(b + c) = ab + ac.

Question: How do you solve a system of linear equations?

Answer: You can solve a system of linear equations by substitution, elimination, or graphing.

Question: What is the difference between a mean, median, and mode?

Answer:

• The mean is the average of a set of numbers.
• The median is the middle number when the numbers are ordered.
• The mode is the number that appears most frequently.

Question: How do you convert a decimal to a fraction?

Answer: To convert a decimal to a fraction, write the decimal as a fraction with a denominator of 1, then multiply both the numerator and denominator by 10, 100, etc., to eliminate the decimal point.

Question: How do you find the square root of a number?

Answer: The square root of a number is a value that, when multiplied by itself, gives the original number.
For example, the square root of 9 is 3.

Question: What is a ratio and proportion in mathematics?

Answer: A ratio is a comparison of two quantities, while a proportion is an equation that shows two ratios are equal.

Question: How do you calculate simple interest?

Answer: Simple interest is calculated using the formula:
Interest = (Principal × Rate × Time) / 100.

Question: What is the difference between speed and velocity?

Answer: Speed is the distance traveled per unit of time, while velocity is speed with a specified direction.

Question: How do you calculate the probability of an event?

Answer: Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Question: What is a linear equation?

Answer: A linear equation is an equation where the highest power of the variable is 1, and the equation graphs as a straight line.

Question: How do you calculate the distance between two points on a coordinate plane?

Answer: The distance between two points (x₁, y₁) and (x₂, y₂) is calculated using the distance formula:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²].

Question: How do you solve an equation with fractions?

Answer: To solve an equation with fractions, multiply both sides of the equation by the least common denominator (LCD) to eliminate the fractions.

Question: What is the formula for the volume of a cylinder?

Answer: The volume of a cylinder is calculated using the formula:
Volume = π × radius² × height.

Question: What is the difference between direct and inverse variation?

Answer: In direct variation, as one quantity increases, the other increases. In inverse variation, as one quantity increases, the other decreases.

Question: How do you solve word problems in mathematics?

Answer: To solve word problems, read the problem carefully, identify the relevant information, form an equation, and solve it step by step.

Question: What is a mixed fraction?

Answer: A mixed fraction is a whole number combined with a fraction.
For example, 2 1/3 is a mixed fraction.

Question: How do you add and subtract fractions?

Answer: To add or subtract fractions, first make sure the denominators are the same. Then, add or subtract the numerators and keep the denominator the same.

Question: What is the difference between permutation and combination?

Answer: A permutation is an arrangement of objects in a specific order, while a combination is a selection of objects without regard to the order.

Question: What is a quadratic formula?

Answer: The quadratic formula is used to solve quadratic equations:
x = (-b ± √(b² - 4ac)) / 2a.
