A basic proficiency in maths is necessary in daily life. Basic maths is needed in most jobs and a higher level of maths opens the door to many rewarding careers. Mathematics is particularly useful in describing behaviour of the natural world and helps us understand and predict impacts of such things as the climate emergency and pandemics.<\/p>\n<p>Maths Week
