1. Addition
- Definition: The process of finding the total or sum by combining two or more numbers.
- Example: 5 + 3 = 8
2. Subtraction
- Definition: The process of finding the difference between two numbers by removing one from the other.
- Example: 9 - 4 = 5
3. Multiplication
- Definition: The process of finding the total of one number multiplied by another.
- Example: 6 × 7 = 42
4. Division
- Definition: The process of determining how many times one number is contained within another.
- Example: 20 ÷ 4 = 5
5. Fraction
- Definition: A number that represents a part of a whole, consisting of a numerator and a denominator.
- Example: 1/2 (one-half)
6. Decimal
- Definition: A number that includes a decimal point, representing a fraction of 10.
- Example: 0.75 (seventy-five hundredths)
7. Percentage
- Definition: A fraction expressed as a part of 100.
- Example: 50% is equivalent to 1/2.
8. Area
- Definition: The amount of space inside a two-dimensional shape, measured in square units.
- Example: The area of a rectangle is found using the formula length × width.
9. Perimeter
- Definition: The distance around a two-dimensional shape.
- Example: The perimeter of a rectangle can be calculated as 2(length + width).
10. Volume
- Definition: The amount of space occupied by a three-dimensional object, measured in cubic units.
- Example: The volume of a cube is found using the formula side × side × side.
11. Angle
- Definition: The figure formed by two rays with a common endpoint, measured in degrees.
- Example: A right angle measures 90 degrees.
12. Symmetry
- Definition: A property where one shape becomes exactly like another if you flip, slide, or turn it.
- Example: A butterfly exhibits symmetry.
13. Mean
- Definition: The average of a set of numbers, calculated by dividing the sum of the numbers by the count of numbers.
- Example: The mean of 2, 3, and 5 is (2 + 3 + 5)/3 = 10/3 ≈ 3.33.
14. Median
- Definition: The middle number in a sorted list of numbers.
- Example: In the set {1, 3, 3, 6, 7, 8, 9}, the median is 6.
15. Mode
- Definition: The number that appears most frequently in a set.
- Example: In the set {1, 2, 2, 3, 4}, the mode is 2.
