## Online Tutoring Is The Easiest, Most Cost-Effective Way For Students To Get The Help They Need Whenever They Need It.

Integers are all positive and negative numbers occur on a number line. A number line represents all the integers. So they are the negative and positive whole numbers. We do not include any fractions in the integers. So numbers like -3, -8, 0, 99, 345 are all integers and ¾, 7,33 and 45/87 are not considered as integers.

The following examples will show how to add and subtract integers.

Example 1:-Sam had \$15 and he went to the store and purchased a candy for \$6. He met his friend there which gave him \$5 which he borrowed from him. What is the total amount of money Sam now have?

Solution 1:-Sam had \$15 in the beginning, he purchased \$6 for a candy.

Total amount left with him is 15 – 6 = \$9

He met his friend who gave him \$5 back

Total amount he has now = 9 + 5 = \$14

Hence total amount left with Sam is \$14.

Example 2:-Jacky has \$65 in his bank account, he purchased a cd player for \$21 which he sold to his friend for \$25. How much money does Jacky has now?

Solution 1:-The amount of money Jacky has in its account is \$65

So the cost of cd player is \$21

Amount left with him is 65 – 21 = \$44

He sold it to his friend for \$25

Total amount he has now = 44 + 25 = \$69
