Course Introduction: Mathematics is built on numbers. Numbers help us to count objects, measure things, and compare quantities in our everyday lives. To make this possible, people long ago created numeration systems, ways of writing and reading numbers. For example, the Romans used Roman numerals, but today we mostly use the Hindu-Arabic system (0–9).

In studying numbers, we also learn how to work with them through number operations such as addition, subtraction, multiplication, and division. Beyond whole numbers, we use fractions and decimals to describe parts of a whole, and we apply ratios and proportions to compare quantities and solve real-life problems.

By the end of this topic, students should be able to:

1. Explain the meaning of numbers and identify different numeration systems.
2. Perform basic number operations (addition, subtraction, multiplication, and division).
3. Understand and apply fractions and decimals in solving problems.
4. Use ratios and proportions to compare quantities and solve real-life situations.
5. Appreciate the importance of numbers in daily activities and mathematical reasoning
