LESSON 0: INTRODUCTION TO ALGEBRA AND NUMBER
CLASSIFICATION (MAT 204) 2025/2026 WITH 100%
ACCURATE QUESTIONS AND ANSWERS
Algebra-correct answersA branch of mathematics dealing with symbols and the rules for using them;
uses variables to generalize problems and solve equations.
Variable-correct answersA symbol used to represent an unknown quantity that can change within a
problem.
Independent variable-correct answersA variable that can be changed freely and does not depend on
other variables in the relation.
Dependent variable-correct answersA variable whose value depends on the independent variable.
Function-correct answersA relation that assigns exactly one output to each input; links inputs to a single
output; often written as y = f(x).
y = f(x)-correct answersNotation for a function; reads as output y is a function of input x.
Numerals-correct answersSymbols used to represent numbers, such as the numeral 5 for the number
five.
Real numbers-correct answersNumbers on the real number line used in everyday life, including
measurements like length, weight, and temperature.
Imaginary numbers-correct answersNumbers not seen in real life, used in advanced mathematics.
Set-correct answersA collection of objects written in braces { }; a set contains its elements.
