Course description

Class 8th Mathematics helps students move from basic concepts to more advanced problem-solving. The syllabus includes topics such as rational numbers, exponents and powers, square roots, algebraic expressions and identities, factorization, linear equations, geometry, mensuration, and data handling. Through practice and application, students improve logical reasoning, analytical skills, and accuracy in calculations. This stage strengthens their foundation and prepares them for the challenges of higher-level mathematics in Class 9 and beyond.

What will i learn?

  • Understanding Scientific Notation – Students learn how very small numbers can be expressed in standard form. Concept of Place Value – Reinforces the idea of shifting decimals and its relation to powers of 10. Handling Powers of 10 – Builds accuracy in using positive and negative exponents. Simplification Skills – Students can rewrite long decimals into a compact, usable form. Application in Real Life – Prepares them to deal with very small (or very large) values in science and maths, like distances, speeds, or measurements. Confidence in Number Representation – Strengthens their foundation for higher studies in Mathematics and Science.

Requirements

  • Understanding of Standard Form (Scientific Notation) – Knowing that a number is expressed as 𝑎 × 10 𝑛 a×10 n , where 1 ≤ 𝑎 < 10 1≤a<10. Decimal Placement Skill – Ability to shift the decimal point after the first non-zero digit. Counting Accuracy – Correctly counting how many places the decimal is moved. Knowledge of Powers of 10 – Recognizing that shifting right → negative power, shifting left → positive power. Application in Simplification – Ability to rewrite small decimals as compact, usable numbers.

Frequently asked question

Step 1: Place the decimal after the first non-zero digit. 0.000567 = 5.67 0.000567=5.67 👉 Step 2: Count how many places the decimal has shifted. It moved 4 places to the right. 👉 Step 3: Multiply with 10 − 4 10 −4 . 0.000567 = 5.67 × 10 − 4 0.000567=5.67×10 −4 ✅ Final Answer: 5.67 × 10 − 4 5.67×10 −4
