Add and subtract integers: find the sign<\/strong><\/h2>\n\n\n\n

key notes:<\/p>\n\n\n\n

An integer is a number without a fractional part. Integers can be positive, negative, or zero.<\/p>\n\n\n\n

You can add and subtract integers. Read on to learn how!<\/p>\n\n\n\n

Adding integers on a number line<\/h4>\n\n\n\n

You can use a number line to add integers. Follow these steps:<\/p>\n\n\n\n

    \n
  1. Find the first addend on the number line.<\/li>\n\n\n\n
  2. Add the second addend. To add a positive number, move to the right. To add a negative number, move to the left. The sum is where you land.<\/li>\n<\/ol>\n\n\n\n

    Adding a positive integer<\/h4>\n\n\n\n

    Let’s try it. Add \u20133+5.<\/p>\n\n\n\n

    Find \u20133 on the number line. Since 5 is positive, move 5 units to the right.<\/p>\n\n\n\n

    \"A<\/figure>\n\n\n\n

    Since you land on 2, the sum is 2.<\/p>\n\n\n\n

    So, \u20133+5=2.<\/p>\n\n\n\n

    Adding a negative integer<\/h4>\n\n\n\n

    Let’s try another one. Add 4+(\u20137).<\/p>\n\n\n\n

    Find 4 on the number line. Since \u20137 is negative, move 7 units to the left.<\/p>\n\n\n\n

    \"A<\/figure>\n\n\n\n

    Since you land on \u20133, the sum is \u20133.<\/p>\n\n\n\n

    So, 4+(\u20137)=\u20133.<\/p>\n\n\n\n

    Rules for adding integers<\/h4>\n\n\n\n

    You can add integers without number lines. Use the signs of the addends to help you solve!<\/p>\n\n\n\n
