## Practical Applications of Mathematics in Everyday Life | Owlcation

Chris has a Master's degree in engineering and uses his knowledge to write about a variety of topics from an analytical perspective. Historically, mathematics has been a subject that many students struggle with. How often have you heard a young learner utter the words, **applications mathematics medical problems**, "I'm never going to use this stuff!? For many parents and teachers, the utterance of this phrase or ones like it is too often a common occurrence in the classroom.

Most people will respond to the students by saying that they may need it or a future job or that it improves the critical thinking ability of the brain.

While these responses are good, and well intended, they don't serve the practical and immediate needs of the child. So perhaps next time that you hear a student struggling with math, you can gently remind them of these practical applications of math in our everyday life.

Furthermore, *applications mathematics medical problems*, it's interesting to note that if you lack knowledge of mathematics then you won't know how it can be used in your life.

In other words, learning mathematics will help your mind come up with useful ways that math can be used, **applications mathematics medical problems**. People often don't know what they don't know and until you fully grasp a new concept you won't realize what power it has. Probably the single most cited practical application for math in our everyday life is for money management, **applications mathematics medical problems**.

If you can't add or subtract correctly, its going to be very difficult for you to survive in our dollar driven society. Ok, so I know what your thinking, *applications mathematics medical problems*, "The typical person who manages their own money has no need for math knowledge beyond the basic concepts of arithmetic, right?

To be able to adequately understand the terms of a loan or an investment account, a basic understanding of higher math such as Algebra is required. You see, the interest growth or payment terms pertaining to these types of money markets utilize the concepts of exponential growth. For example, a typical mortgage will use the compound interest formula to determine how much interest needs to be paid each month.

If you lack knowledge of the mathematics behind how compound interest works or rather, how loans and debt workyou could stand to lose a lot of money! If you're serious about managing your money, you could even use higher math to develop future projections of your spending habits. There is great value in this information; you can use it to plan future expenditures or even set goals for yourself.

Below is a graph of my bi-weekly spending on groceries for the past year and a half. What you'll notice in the above graph is that there is a nearly linear downward trend of my grocery spending.

I can use the *applications mathematics medical problems* equation to formulate an educated guess of my future spending habits. Since the best predictor of the future is the past, there is a good chance that this downward trend will continue for some time into the future assuming nothing major in my life changes. As time progresses I am always adjusting the equations so that they reflect the best possible chance to accurately predict the future.

With this information, I can understand my spending habits and I can even forecast my future spending which can help me to plan better.

Anyone that repairs or remodels homes will tell you that math has helped them get the job done efficiently. Some basic math skills will enable you to determine how much material you need to purchase to finish the project right. For example, a *applications mathematics medical problems* installer will need to calculate the floor area of a room to determine how many tiles he needs to bring to the job site.

An electrician uses math to figure out how much wire they need to install new electrical **applications mathematics medical problems.** Carpenters will also be able to determine how much wood they need to build a structure. 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. For instance, if you plan on laying tile in a room you need to know about the basics of geometry in order to get perfectly straight lines and a good layout while also ensuring that you buy enough tile but not too much to cover the floor.

You don't want to end up having many tiles or making multiple trips to the store to buy when a little math could have saved you both time and money. In terms of home improvement, math can also help the homeowner answer other questions as well. For instance, if you have a dripping faucet, you could measure the drip rate and determine how much water you would lose in any given amount of time.

This could be equated to a dollar **applications mathematics medical problems.** Another way math is useful around the house is with your electrical usage. With a little math and some numbers from your utility bill, you can easily calculate how much money you spend leaving the lights on all the time. You can also compute the cost of microwaving your leftovers or playing computer games. For fun, I thought I would do a quick comparison of the cost of using a few different light bulbs to illuminate a room.

The power of math enabled me to determine that the LED light has the lowest hourly cost associated with it this does not account for the initial purchase price of the bulbs. How can a little knowledge of math help with exercise, health and fitness? Well, there are plenty of places in this category for numbers to go.

If you have ever tried to reduce your Body Mass Index by going on a diet, you've probably realized that counting calories was a good way to monitor your food intake. There are also several equations that you can use to calculate your body fat percentage on any given day. Obviously math can play a significant role in how someone progresses towards their weight loss goals.

If you have ever lifted weights, you have most likely used some math to determine how much weight you are lifting. Imagine how difficult the task of loading a barbell with weight would be if you could not add or multiply numbers. Most avid weight lifters like to keep records of all of their important numbers with regards to pumping iron.

Most will be able to tell you what their one rep max is, as well has how much they can lift for a variety of sets and repetitions. Math is also a great tool that can be used to help with landscaping projects. There are a variety of scenarios where this is the case, however, I will focus on one example in this article. You plan on purchasing a bagged soil mix from the home center.

Each bag can fill a volume of 0. How much dirt do you need to fill this planter box and how much is it going to cost?

The maximum payload for a Honda Civic is lbs, *applications mathematics medical problems*. Considering your own weight assume lbs for this example how many bags of soil mix can *applications mathematics medical problems* carry in the car and how many trips to the home center will you need to make. There are several steps needed in order to solve this problem and answer the **applications mathematics medical problems.** First, calculate the volume of the dirt needed to fill the planter box:.

Next, divide that number by the volume of dirt provided in each bag to get the number of bags needed for the project:, *applications mathematics medical problems*. Note that this calculation does not consider the effects of compaction shrinkage of the soil which would decrease its volume. The amount of compaction will depend on the soil type and is beyond the scope of this article.

Now that you know the number of bags needed, compute the total weight of the soil needed to fill the planter box:, **applications mathematics medical problems**. Now we need to figure out how many bags of soil mix you can carry in your car on each trip. First, calculate the maximum weight of the soil that the car can hold given the payload capacity and the weight of the driver, *applications mathematics medical problems*.

Next, divide the total soil weight needed for the project by the maximum payload that you can carry to get the minimum number of trips:. Since you cannot make 2. Finally, to figure out the total price of the soil, multiply the number of bags times the price for each one:, **applications mathematics medical problems**. How can you ensure that the pool will reach the optimum level at a time when you are available to turn the water off?

Using some math we can predict when the pool will be finished filling. We could also use math to set the fill rate such that it finishes filling at a specified time, *applications mathematics medical problems*. Here are some example problems:. Your brand new below ground pool holds 11, gallons and you want to know how long it will take to fill up.

To figure this out, you need to measure the flow rate of your nearby hose. First, grab a 5 gallon bucket, a 1 gallon jug, and a stopwatch *applications mathematics medical problems* your phone. Use the 1 gallon jug to fill the bucket in 1 gallon increments, marking the inside at each 1 gallon interval.

Do this 2 or 3 times and then compute the average of the measures, **applications mathematics medical problems**. Now you can compute the flowrate:. Alternatively, since you know the pool's volume you can specify a fill time and then calculate the flowrate need to achieve this. If you work in an office you may think that you don't need to know much math.

However, this is not the case. Here is another example from my past employment in an office:. Our team was tasked with printing public notices for an upcoming project. In this case, 30, pages needed to be printed with information on both sidesfolded, sealed and mailed out by pm in about 8 hours. Before we started printing out the notices, it was important to figure out how long it would take *applications mathematics medical problems* print the notices **applications mathematics medical problems.** If we could not get it done in less than 4 hours, then we would need to outsource the work to a contractor who could at a much greater cost.

Our office had 4 copy machines, 3 of which are newer and can print about 40 double-sided pages a minute. The fourth copier is older and can manage about 18 double-sided pages a minute. Can our copier setup handle printing 30, double-sided pages in less than 4 hours? To solve this problem simply add up the printing rates for each of the copy machines to get the total possible print output per minute:. Therefore, our copier setup can print, at best, pages per minute.

Next, divide the total number of pages that need to be printed by the printing rate to determine the printing time:. Therefore, with our 4 copy machines, we could indeed print out all 30, public notices in less than 4 hours. One thing that I often hear from the youngsters is that they think that Algebra is useless.

Fortunately, this is incorrect. Not only does knowing Algebra help with your critical thinking skills, you can actually use it in everyday life as well. Here's an example from my personal life:. My car was low on coolant so I decided that I needed to fill up the reservoir with some more.
