What is algebra?
Algebra is a branch of mathematics that generalizes arithmetic by using letters (variables) to represent unknown numbers. It allows formulating general laws and solving problems by manipulating symbolic expressions.
Fundamental concepts of algebra include algebraic expressions, equations, inequalities, factors, powers, and notable identities such as (a+b)² = a² + 2ab + b².
Algebra in the psychometric test
Algebra is the most tested mathematical skill in the psychometric test. It is involved in solving equations, simplifying expressions, factoring, and setting up equations from word problems.
Questions often require combining multiple algebraic techniques: factoring an expression, solving a system of equations, or manipulating inequalities. Speed of calculation is a significant advantage.
Frequently asked questions
What algebra concepts are most tested?
The most common are: solving first and second-degree equations, systems of equations, factoring, notable identities, and manipulating expressions with algebraic fractions.
How can I improve my algebra skills?
Practice daily solving equations and manipulating expressions. Memorize notable identities. Use Hiku's progressive exercises to strengthen your skills step by step.
Is algebra more important than geometry?
Both are tested, but algebra is more frequent and also comes up in geometry problems (setting up equations). Mastering algebra is therefore a priority for maximizing your score.
