Why is it important?

Fractions are regularly used in the world of work and daily life.
Decimal fractions are important for conversions in measurement and money and understanding what proportion of a whole is represented. It is also important when interpreting answers on calculators.
Percentages: used in a wide variety of contexts, many of which are used in everyday life.
The ability to interchange between a fraction, decimal fraction and percentage is a skill that allows for different ways to solve problems efficiently, including mental calculations.

Expressions and Equations
Why is it important? Understanding that numbers, and operators, can be replaced by pictures or symbols is fundamental to all algebraic thinking. Finding the unknown quantity, or operator, is an essential step in developing the ability to work with expressions and solve equations. Many problems involve a number of algebraic terms. Being able to simplify the combination of terms makes solving the problem considerably less challenging. Being able to use formulae is essential in many areas of the curriculum and supports the type of problem solving skills needed in many jobs in the modern world.
How is this used in real life contexts?
Computers were invented to solve equations over and over again instead of humans doing thecalculations.
