MATHS IN DAILY LIFE

When am I ever going to use this?

Variations of this question have echoed through the halls of math classrooms everywhere. Struggling students often become frustrated with complex math problems and quickly give in to the notion that they will never use math in “real life” situations. While it may be true that some of the more abstract mathematical concepts rarely come into play, the underlying skills developed in high school math classrooms resonate throughout a student’s lifetime and often resurface to help solve various real world or work-related problems sometimes years down the line.

1. Ask any contractor or construction worker and they’ll tell you just how important math is when it comes to building anything. Creating something that will last and add value to your home out of raw materials requires creativity, the right set of tools, and a broad range of mathematics.

   

    Figuring the total amount of bags of concrete needed for a slab, accurately measuring lengths,       widths, and angles, and estimating project costs are just a few of the many cases in which math is necessary in real life home improvement projects.

2.One of the more obvious places to find people using math in everyday life is at your neighborhood grocery store. Grocery shopping requires a broad range of math knowledge from multiplication to estimation and percentages.
Calculating price per unit, weighing produce, figuring percentage discounts, and estimating the final price are all great ways to include the whole family in the shopping experience.

Encourage your students to play math challenges at the grocery store with their family by attempting to estimate the total cost of all groceries prior to checkout. The difficulty can be increased by incorporating coupons, sales, and adjusted pricing for bulk items. Your little bargain shoppers will thank you later when they’re saving money on their own groceries.

3.

More math can be found in the kitchen than anywhere else in the house. Cooking and baking are sciences all their own and can be some of the most rewarding (and delicious) ways of introducing children to mathematics. After all, recipes are really just mathematical algorithms or self-contained step-by-step sets of operations to be performed.

The proof is in the pudding!

Working in the kitchen requires a wide range of mathematical knowledge, including but not limited to:

• measuring ingredients to follow a recipe
• multiplying / dividing fractions to account for more or less than a single batch
• converting a recipe from Celsius to Fahrenheit
• converting a recipe from metric (mL) to US standard units (teaspoon, tablespoon, cups)
• calculating cooking time per each item and adjusting accordingly
• calculating pounds per hour of required cooking time
• understanding ratios and proportions, particularly in baking (ex. the recipe calls for 1 egg and 2 cups of flour, then the ratio of eggs to flour is 1:2).

Following a recipe can sometimes be tricky, especially if conversions are necessary. We Americans follow our own set of rules when it comes to most forms of measurement. Conversions make it a bit more difficult to follow recipes from other countries as they most likely use Celsius and the metric system.

Indian Mathematicians

Srinivasa Ramanujan

Srinivasa Ramanujan is one of the celebrated Indian mathematicians. His important contributions to the field include Hardy-Ramanujan-Littlewood circle method in number theory, Roger-Ramanujan’s identities in partition of numbers, work on algebra of inequalities, elliptic functions, continued fractions, partial sums and products of hypergeometric series.

C.R. Rao
Calyampudi Radhakrishna Rao, popularly known as C R Rao is a well known statistician, famous for his “theory of estimation”.

D. R. Kaprekar

D. R. Kaprekar discovered several results in number theory, including a class of numbers and a constant named after him. Without any formal mathematical education he published extensively and was very well known in recreational mathematics cricle

Indian Mathematicians

It is no doubt that the world today is greatly indebted to the contributions made by Indian mathematicians. One of the most important contribution made by them was the introduction of decimal system as well as the invention of zero. Here are some the famous Indian mathematicians dating back from Indus Valley civilization and Vedas to Modern times.
Aryabhata

Aryabhata worked on the place value system using letters to signify numbers and stating qualities. He discovered the position of nine planets and stated that these planets revolve around the sun. He also stated the correct number of days in a year that is 365.

Brahmagupta
The most significant contribution of Brahmagupta was the introduction of zero(0) to the mathematics which stood for “nothing”.

Inspiring Mathematicians

Leonhard Euler (1707- 1783)
The most prolific mathematician of all time, publishing close to 900 books. When he went blind in his late 50s his productivity in many areas increased. His famous formula eiπ + 1 = 0, where e is the mathematical constant sometimes known as Euler's number and i is the square root of minus one, is widely considered the most beautiful in mathematics. He later took an interest in Latin squares – grids where each row and column contains each member of a set of numbers or objects once. Without this work, we might not have had sudoku.

Carl Friedrich Gauss (1777-1855)

Known as the prince of mathematicians, Gauss made significant contributions to most fields of 19th century mathematics. An obsessive perfectionist, he didn't publish much of his work, preferring to rework and improve theorems first. His revolutionary discovery of non-Euclidean space (that it is mathematically consistent that parallel lines may diverge) was found in his notes after his death. During his analysis of astronomical data, he realised that measurement error produced a bell curve – and that shape is now known as a Gaussian distribution.
