04 CBSE Aggarwal class 6 Chapter Integers exercise 4b Sum 4,5
Integers are a type of number that includes all positive and negative whole numbers, as well as zero. They can be represented on a number line, where positive integers are to the right of zero and negative integers are to the left of zero. Integers can be added, subtracted, multiplied, and divided like other numbers, but there are some special rules to follow when working with integers.
Some important rules to remember when working with integers include:
When you add two positive integers, the sum is positive.
When you add two negative integers, the sum is negative.
When you add a positive integer and a negative integer, you subtract their absolute values and take the sign of the larger integer.
When you subtract one integer from another, you can add the opposite of the second integer.
When you multiply two integers, the product is positive if the signs of the two integers are the same, and negative if the signs are different.
When you divide two integers, the quotient is positive if the signs of the two integers are the same, and negative if the signs are different.
When dividing by zero, the result is undefined.
Integers are used in many different areas of math and science, including algebra, geometry, and physics. They are also used in everyday life, such as in banking and finance, where positive and negative numbers represent money earned and spent.
