How much change are they each left with? It turns out we can use a simple algebraic equation to figure this problem out quickly and easily. For this example, we are going to represent the change they are left with using the letter x any letter will do — x just happens to be a popular choice. The total change will, therefore, be represented by 2x because they need to divide it between themselves.

There are 26 cats in the pet shop. This is two more than three times the number of dogs. How many dogs are there in the pet shop? Alice and Bob have some candy. If Alice gives Bob a piece of candy, Bob has twice as much candy as her.

Algebra: Using Mathematical Symbols

If Bob gives Alice a piece of candy, they have the same number. How many pieces of candy do they each have? When getting your child to attempt these questions, always ask them to show their reasoning, as this is the essence of algebra and indeed of all mathematics! In the last example, they may solve the problem through trial and error. Algebra becomes really powerful when it gives us systematic methods that can be applied to a flexible range of problems.
