When setting the alarm or hitting snooze, people quickly need to calculate the new time they will rise. People on medication need to understand their dosage amount, whether in grams or millilitres. Recipes call for ounces and cups and teaspoons — all measurements meaning all maths. Moreover, decorators need to know that the dimensions of their furnishings and rugs will match the area of their rooms.
Travellers might need to calculate a new route if faced with detours and consider the additional cost in miles, time and money. Air travellers need to know departure times and arrival schedules as well as the weight of their luggage (unless they want to risk some hefty baggage charges!).
At School and Work
Students can’t avoid math as they take it every day. However, there are other classes (such as History or English) which require a little maths as well. Jobs in business and finance may require sophisticated knowledge of how to read profit and earning statements, which is maths too. Even hourly earners will need to know if their working hours multiplied by their rate of pay accurately reflects their paychecks.
At the store
Whether buying coffee or a car, basic principles of math are in play. Purchasing decisions require some understanding of budgets and the cost and affordability of items from groceries to houses.
Even off-time can be math time. Baseball fans know a lot about statistics and football fans know about yardage gains and passing stats. Individual athletes, whether runners, bikers, sailors or hikers, often have ways of charting their progress, from time to mileage to elevation.
Probably the single most cited practical application for math in our everyday life is for money management. If you can't add or subtract correctly, its going to be very difficult for you to survive in our dollar driven society.
Anyone that repairs or remodels homes will tell you that math has helped them get the job done efficiently. Some necessary math skills will enable you to determine how much material you need to purchase to finish the project right. You will likely rely on some form of math, even when you are doing something as simple as painting a room. Understanding basic math concepts will help any do-it-yourselfer save time and money.
