Addition Basics Quiz

Addition

Definition

• Addition is a basic arithmetic operation that represents the combination of two or more values to get a total or a sum.
• It is denoted by the plus sign (+).

Properties

• Commutative Property: The order of the numbers being added does not change the result.
  • Example: 2 + 3 = 3 + 2
• Associative Property: The order in which numbers are added does not change the result when more than two numbers are added.
  • Example: (2 + 3) + 4 = 2 + (3 + 4)
• Distributive Property: Addition can be distributed over multiplication.
  • Example: 2 + 3 × 4 = 2 + 12

Types of Addition

• Whole Number Addition: Adding whole numbers (positive integers).
  • Example: 5 + 2 = 7
• Fraction Addition: Adding fractions (numbers with a numerator and a denominator).
  • Example: 1/2 + 1/4 = 3/4
• Decimal Addition: Adding decimal numbers (numbers with a fractional part).
  • Example: 2.5 + 1.8 = 4.3

Real-World Applications

• Counting objects: Adding the number of objects in different groups.
• Measuring quantities: Adding lengths, weights, or capacities of different objects.
• Financial calculations: Adding amounts of money.

Key Concepts

• Sum: The result of adding two or more numbers.
• Addend: A number being added to another number.
• Augend: The number to which another number is being added.
