Using brackets

Let’s see how brackets can be used to solve mathematical problems.

Example: Bianca wants to buy 2 cupcakes for each of her cousins and friends. She has 18 cousins and 23 friends in all. How many cupcakes do you think she should buy in all?

First, we need to find the total number of people that Bianca wants to buy cupcakes for. The total number of people = Number of cousins + Number of friends

= 18+23

As each person gets 2 cupcakes, the total number of cupcakes Bianca has to buy is Total cupcakes = (18 + 23) x 2 = 82.

Introducing brackets because the total number of people has to be multiplied by the number of cupcakes each person has in order to get the total number of cupcakes.

If we do not put brackets here, then the total number of cupcakes becomes, 18 + 23 x 2 = 64, which is incorrect. This is why we have to use brackets while solving mathematical problems.
