Basic Addition Facts

Addition is the arithmetic operation of combining two or more numbers to produce a new total. It is a fundamental skill in mathematics and is used extensively in various fields. This article will focus on the basics of addition, including common addition facts, addition rules, and drills for practice.

Common Addition Facts

Adding Single Digits

When adding single-digit numbers, you can use the basic addition facts to find the sum. These facts are:

• 1 + 1 = 2
• 1 + 2 = 3
• 1 + 3 = 4
• 1 + 4 = 5
• 1 + 5 = 6
• 1 + 6 = 7
• 1 + 7 = 8
• 1 + 8 = 9
• 1 + 9 = 10

Adding Double Digits

For double-digit numbers, you can use the following facts:

• 2 + 2 = 4
• 2 + 3 = 5
• 2 + 4 = 6
• 2 + 5 = 7
• 2 + 6 = 8
• 2 + 7 = 9
• 2 + 8 = 10
• 2 + 9 = 11

Adding Three-Digit Numbers

When adding three-digit numbers, you can follow these addition facts:

• 3 + 2 = 5
• 3 + 3 = 6
• 3 + 4 = 7
• 3 + 5 = 8
• 3 + 6 = 9
• 3 + 7 = 10
• 3 + 8 = 11
• 3 + 9 = 12

Addition Rules

Commutative Property

The commutative property states that the order of the numbers being added does not affect the sum. For example:

• 3 + 4 = 7
• 4 + 3 = 7

Associative Property

The associative property states that the grouping of numbers being added does not affect the sum. For example:

• (3 + 4) + 5 = 12
• 3 + (4 + 5) = 12

Distributive Property

The distributive property allows you to multiply a number by the sum of two or more numbers. For example:

• 3 × (4 + 5) = 3 × 9 = 27

Addition Drills

Practice is essential for mastering addition skills. Some ways to practice include:

• Adding single-digit numbers
• Adding double-digit numbers
• Adding three-digit numbers
• Solving addition word problems
• Using addition drills and exercises provided in textbooks or online resources

By consistently practicing addition facts and rules, you can improve your understanding and proficiency in this fundamental arithmetic operation.
