Remember when you were sitting in your math class and you thought you’d never use that lesson in the real world? Many consider mathematics to be a universal language. Whether you believe it or not, here are lessons you use in the real world everyday!


Math is continually used in the kitchen when baking or preparing a meal. When doubling or making half of a recipe, multiplication or division comes into play. Perhaps someone might desire to create an exotic meal. However, the ingredients are listed using the metric system. In order to ensure the right quantities of different items, conversion to the U.S. standard equivalents must occur. Maybe a baking temperature is recorded as Celsius. A cook would have to convert the temperature into Fahrenheit. Poultry roasting directions are commonly listed as requiring so many minutes per each pound. Once again, multiplication is used to determine the time needed to properly bake the bird.

DIY Projects

Math is needed for many types of home improvement projects. If planning on painting a room, one must calculate the amount of space to be covered with paint to know how many gallons of paint are needed. Building anything requires calculating the amount of raw materials needed to complete the project. Measurements are made before cutting the materials and carrying out the construction process.

Road Trips

Calculations are commonly used before embarking on an excursion. Travelers determine the number of miles from one location to the next. They might divide that number by the speed limit to estimate time of arrival. Knowing how much a vehicle’s gas tank holds helps drivers plan on how many times they must stop for gas along the way before arriving at their final destination. Math is also used to estimate expenses for meals, fuel and the possible need for accommodations.

Money Management

Each time money is added to an account, addition is needed to find the current balance. Likewise, when paying monthly bills or making purchases, subtraction is necessary in order to keep from having more debits than deposits. When making purchases on credit, math is needed to determine the interest rate that will be added to the overall price of the purchase.
