Fourth Year Mathematics Notes
Mathematics is the study of numbers, patterns, shapes, and logical reasoning. It helps students
solve problems and make decisions in everyday life.
Algebra
Algebra uses letters and symbols to represent numbers.
Example: x + 5 = 12
To solve for x, subtract 5 from both sides:
x=7
Functions
A function is a rule that assigns one output to each input. Example: f(x) = 2x + 3
If x = 4, then f(4) = 11.
