Mathematics has been part of human understanding for over two thousand years, both in describing the natural world and through logical reasoning. In recent centuries, mathematics has also been successfully applied to other human endeavors like politics, archaeology, transportation, and environmental management. Today, mathematical thinking is even more valuable as a way to understand and express ideas. Learning mathematics is essential for a well-rounded education. The document then provides examples of how mathematics applies to everyday situations like comparing unit prices at the grocery store to identify the best deals. Unit rates allow direct comparison of item costs for different quantities. Examples demonstrate using unit rates to determine which olive oil, nuts, or flour offers the best value.

2. INTRODUCTION
For more than two thousand years, mathematics has been a part of
the human search for understanding. Mathematical discoveries have
come both from the attempt to describe the natural world and from
the desire to arrive at a form of inescapable truth from careful
reasoning. These remain fruitful and important motivations for
mathematical thinking, but in the last century mathematics has been
successfully applied to many other aspects of the human world: voting
trends in politics, the dating of ancient artifacts, the analysis of
automobile traffic patterns, and long-term strategies for the
sustainable harvest of deciduous forests, to mention a few. Today,
mathematics as a mode of thought and expression is more valuable
than ever before. Learning to think in mathematical terms is an
essential part of becoming a liberally educated person.

3. MATHEMATICS IN DAILY LIFE
• Maths is all around us, it is everywhere we go.
• Not only does maths underline every process
and pattern that occurs in the world around
us, but also, a good understanding of it will
help enormously in our daily life.
• Being fast in mental arithmetic can save your
money when you go to market.

4. UNIT RATES IN EVERYDAY LIFE
• We sometimes will be at the grocery store and will be
staring at two different items wondering which one is
the best deal.
• Discount :-
 Offers during festival seasons.
 If you buy many, get one free/two free.
 If you buy for more amount, more discount.
• If so, a UNIT RATE could help out when this happens
and make your purchasing decision an easy one.
• Now we will know what are UNIT RATES are and how
to apply them in everyday comparison situations.

5. UNIT RATES
• To find the Unit Rate, you would find the cost or
amount for 1. Or the rate when the denominator
is 1.
“How much for just 1?”
• If it costs Rs.78 for 13 sandwiches, What is the
unit rate?
Rs.78 ÷ 13 = 𝑅𝑠. 6 𝑒𝑎𝑐ℎ

6. AT THE GROCERY STORE
