    IGCSE Maths Number & Arithmetic Tutor

    Number topics in IGCSE Maths 0580 form the bedrock of the paper — they appear on every paper across all tiers. Strong number skills build confidence and free up mental capacity for harder topics. Our tutors systematically strengthen every area from fractions and percentages to surds and indices.

    Board: Cambridge IGCSE

    Topics Covered

    • Integers, fractions and decimals
    • Percentages and percentage change

    Exam Tips

    • Tip 1:Percentage increase/decrease: multiply by the multiplier — e.g. 20% increase = × 1.2
    • Tip 2:Standard form: coefficient must be between 1 and 10
    • Tip 3:Surds: rationalise denominator by multiplying by conjugate
    • Tip 4:Bounds: lower bound = value - ½ × accuracy; upper bound = value + ½ × accuracy
