Do we really need Math when we grow up? When I was growing up, I really did not care for math. At a young age I realized that I must study and practice all the time to truly understand math. Math is a tricky subject like that, if you do not practice it all the time you tend to forget it. I also asked myself one day, ‘Do we really need to have a good foundation of math, and will we need it when we grow up? ” When we are older adults, are we going to need Math knowledge in our everyday life, or in our jobs?
When I was young, I never thought that you would need Math in any career when you’re an adult. Now I know that I was all wrong. In this paper I will discuss how we need Math in our everyday living, and in certain careers that you might not have thought that math was used. We as human being need to eat to live and survive. We cannot just go to fast food restaurants and order from the menu all the time, that is to unhealthy. Some time in life, you must learn how to cook. There are many different ways to learn how to cook; if it is not from your Mother then it is for another source like TV, the Inter Net, a cookbook, or a cooking class.
To create dishes with good flavor, consistency, and texture, the various ingredients must have a kind of relationship to one another. For instance, to make cookies that both look and taste like cookies, you need to make sure you use the right amount of each ingredient. Add too much flour and your cookies will be solid as rocks. Add too much salt and they’ll taste terrible. All ingredients have relationships to each other in a recipe and are an important concept in cooking. It’s also an important math concept. In math, this relationship between 2 quantities is called a ratio.
If a recipe calls for 1 egg and 2 cups of flour, the relationship of eggs to cups of flour is 1 to 2. In mathematical language, that relationship can be written in two ways: 1/2 or 1:2 Both of these express the ratio of eggs to cups of flour: 1 to 2. If you mistakenly alter that ratio, the results may not be edible. All recipes are written to serve a certain number of people or yield a certain amount of food. You might come across a cookie recipe that makes 2 dozen cookies, for example. What if you only want 1 dozen cookies? What if you want 4 dozen cookies?
Understanding how to increase or decrease the yield without spoiling the ratio of ingredients is a valuable skill for any cook. If you want to make 9 dozen cookies, you’ll have to increase the amount of each ingredient listed in the recipe. You’ll also need to make sure that the relationship between the ingredients stays the same. To do this, you’ll need to understand proportion. A proportion exists when you have 2 equal ratios, such as 2:4 and 4:8. Two unequal ratios, such as 3:16 and 1:3, don’t result in a proportion. The ratios must be equal. Cooking is not the only way we use math, what about in a career?
Both doctors and nurses use math every day while providing health care for people around the world. Doctors and nurses use math when they write prescriptions or administer medication. Medical professionals use math when drawing up statistical graphs of epidemics or success rates of treatments. Math applies to x-rays and CAT scans. Numbers provide a lot of information for medical professionals. It is reassuring for the general public to know that our doctors and nurses have been properly trained by studying mathematics and its uses for medicine. Regularly, doctors write prescriptions to their patients for various usages.
Prescriptions indicate a specific medication and dosage amount. Most medications have guidelines for dosage amounts in milligrams (mg) per kilogram (kg). Doctors need to figure out how many milligrams of medication each patient will need, depending on their weight. If the weight of a patient is only known in pounds, doctors need to convert that measurement to kilograms and then find the amount of milligrams for the prescription. There is a very big difference between mg/kg and mg/lbs, so it is important that doctors understand how to accurately convert weight measurements.
Doctors must also determine how long a prescription will last. For example, if a patient needs to take their medication, say one pill, three times a day. Then one month of pills is approximately 90 pills. However, most patients prefer two or three month prescriptions for convenience and insurance purposes. Doctors must be able to do these calculations mentally with speed and accuracy. Cooking and Medicine are only a few ways that math is used in our lives. There are many different jobs that use math, and many different ways we use math in our everyday life.
It is very important that you learn the foundation of math, and try to stay sharp with it. If you want to live long and have a good career, you must truly understand math to its full extent.
