## Examples of uses of plus and minus sign

The signs of integers, that is the plus and minus sign convey a precise meaning when used in certain situations.

Let us understand this with the following examples:

Q. Amir received ₹ 500 as pocket money, of which he spent ₹ 200. What signs

would indicate the money he received and spent?

Solution:

Amir has received the money. This means he has more money now than he had earlier. Since it is an increase, it will be denoted with a plus sign, that is +500.

Spending ₹ 200 has reduced Amir’s pocket money by ₹ 200. Since it is a decrease it will be

denoted with a minus sign, that is -200.

Q. Rahul and Bianca started a new business. What sign would we use to show a

loss of ₹ 10,000 and a profit of ₹ 10,000?

Solution:

Since loss means ‘to lose’, if Rahul and Bianca’s business made a loss, it would be shown as

-10,000.

Profit means ‘to gain’, so if they made a profit it would be shown as +10,000.
