Solving Equations: 20 April
Why are equations important in every day life?
An equation is the mathematical representation of two things which are equal, one on each side of an ‘equals’ sign. Equations are useful to solve our daily life problems.
Example: How might we express this as an equation?
You're a Wedding Planner. The top table will be the Bride & Groom, Best Man, Bridesmaid and the Bride's parents plus the Groom's Dad. You have 56 other guests to accomodate for the meal. You have a maximum of 10 tables How can you make sure each table has the same number of people and how many tables will you need?
