Videos, worksheets, stories and solutions to help Grade 6 students learn how to add integers using rules. The rules are

1. The sum of two or more positive integers is a positive integer

2. The sum of two or more negative integers is a negative integer

3. To find the sum of a negative and positive integer: (ignore the signs) subtract the smaller number from the bigger number and keep the sign of the larger number.

The rules for adding integers

Examples:

2 + 3, -5 + (-8), 10 + (-7), 16 + (-21), -4 + (-5) + (-1), -7 + (-4) + 12, 8 + 3 + (-15), 2 + (-3) + 4, (-4) + 3 + (-6), 10 + (-18) + (-4)
The rules for adding integers

Examples:

-5 + 9, -3 + (-2), 8 + (-7), 10 + (-3), -4 + (-8), -1 + 5

Evaluate*n* + (-2) for each value of *n*.

This video explains how to add integers using formal rules for adding integers.

Rules for Addition of Integers

A. If you are adding two integers of the same sign

1. Add their absolute values

2. Keep the sign of the original integers

B. If you are adding two integers with different signs

1. Find the absolute value of both

2. Subtract the smaller value from the larger value

3. The sign of the answer is the original sign of the number with the larger value.
This video provides example of adding integers using a money analogy and the formal rules for adding integers.
