Study Notes
Mathematics
Mathematics is the study of numbers, quantities, structures, and relationships. It has applications in various fields such as science, engineering, finance, and economics. There are several fundamental concepts within mathematics, including whole numbers and fractions.
Whole Numbers
Whole numbers are non-negative integers, which means they start from zero and continue indefinitely upwards. They can represent counts, measures, or groups and have many real-life applications. For example, when counting the number of students in a class or measuring the length of a room in meters, you would typically work with whole numbers. In mathematical notation, whole numbers are represented by the set of natural numbers, denoted N.
Fractions
Fractions are a way of representing parts of a whole. They consist of two components: a numerator, which represents the part, and a denominator, which represents the whole. For instance, if you cut a pizza into eight slices and eat three slices, you've eaten 3 out of 8 pieces, or 3/8 of the pizza. This is equivalent to 37.5%, where 3 is the fraction's numerator, 8 is its denominator, and 0.375 is the decimal representation of the fraction.
In more complex mathematical expressions, fractions can be raised to powers, multiplied together, divided, and added or subtracted. Learning how to manipulate these operations is crucial for understanding advanced math problems and solving them correctly.
