Addition is a fundamental operation in mathematics that involves combining numbers to find their sum. When adding two or more numbers, the result is called the sum. The symbol used to denote addition is +.

To add two or more numbers, line up the numbers vertically according to their place value (ones, tens, hundreds, etc.) and then add the numbers in each column, starting from the rightmost column (ones).

For example, to add 23 and 54:

23 + 54 ____ 77

Sometimes when adding numbers, the sum of a column may be greater than 9. In such cases, the extra value is carried over to the next column on the left.

For example, to add 48 and 57:

48 + 57 _____ 105

**Understand Place Value:**Before adding numbers, make sure you understand the place value of each digit in the numbers.**Line Up Numbers:**When adding multiple numbers, line them up vertically according to their place value.**Add from Right to Left:**Start adding from the rightmost column (ones) and move left, adding each column one at a time.**Carry Over When Necessary:**If the sum of a column is greater than 9, carry over the extra value to the next column on the left.**Practice, Practice, Practice:**The more you practice addition, the more comfortable and confident you'll become with this fundamental operation.

By mastering addition, you'll build a strong foundation for tackling more complex mathematical concepts in the future.

Algebra: Writing, interpreting, and using mathematical expressions and equations

Students write mathematical expressions and equations that correspond to given situations, they evaluate expressions, and they use expressions and formulas to solve problems. They understand that variables represent numbers whose exact values are not yet specified, and they use variables appropriately. Students understand that expressions in different forms can be equivalent, and they can rewrite an expression to represent a quantity in a different way (e.g., to make it more compact or to feature different information). Students know that the solutions of an equation are the values of the variables that make the equation true. They solve simple one-step equations by using number sense, properties of operations, and the idea of maintaining equality on both sides of an equation. They construct and analyze tables (e.g., to show quantities that are in equivalent ratios), and they use equations to describe simple relationships (such as 3x = y) shown in a table.
