Algebra - Main Topics Covered The CSEC Mathematics syllabus - CSEC Mathematics exam
Algebra 🧮 1. Algebra ✳️ Equations An equation shows that two expressions are equal. Example: Solve: 2x+3=112 x +3=11 Solution: Subtract 3: 2x=82 x =8 Divide by 2: x=4 x =4 ✳️ Inequalities Inequalities compare expressions using symbols like >, <, ≥, ≤. Example: Solve: 3x−5<103 x −5<10 Add 5: 3x<153 x <15 Divide by 3: x<5 x <5 ✳️ Factorization This means writing an expression as a product of its factors. Example: Factor: x2+5x+6 x 2+5 x +6 Find two numbers that multiply to 6 and add to 5: (2 and 3) So: (x+2)(x+3)( x +2)( x +3) ✳️ Algebraic Expressions These are combinations of variables, numbers, and operations. Example: Simplify: 3x+2x−53 x +2 x −5 Combine like terms: 5x−55 x −5 📐 2. Geometry ✳️ Angles A straight line = 180° A triangle = 180° A right angle = 90° Example: If one angle in a triangle is 50° and a...
