More about Class 8 Maths Chapter 1

8th Maths Chapter 1 deals with the use of various terms of simple Maths. It teaches about property of addition, subtraction and Products. We will work on Commutative and other properties. Learn the rules are under addition and Product. In all the ways we have to check terms. For example, if Identity, Inverse exist or not.
Student learn here the use of additive identity or inverse. We work on the approach of distributive property. We learn here the ways to show rational number on a number line. Get the rational number between any two rational numbers. We know that there are countless rational numbers between two. Using the idea of mean, we find the numbers between two rational numbers.

About Preparation of Class 8 Maths Chapter 1

Commutative and associative rules students will have to apply in other lessons also, so learn it well. It should also be known to find the additive inverse and multiplicative inverse of different rational numbers. Students can contact anytime for any problem related to the study. There is no need to hesitate. Our main purpose is your help.

Associative Property of Integers
Operation Numbers Remarks
AdditionIs (–2) + [3 + (– 4)] = [(–2) + 3)] + (– 4)? Is (– 6) + [(– 4) + (–5)] = [(– 6) +(– 4)] + (–5)? For any three integers a, b and c, we have a + (b + c) = (a + b) + cAddition is associative
Subtraction Is 5 – (7 – 3) = (5 – 7) – 3? No.Subtraction is not associative
MultiplicationIs 5 × [(–7) × (– 8) = [5 × (–7)] × (– 8)? Is (– 4) × [(– 8) × (–5)] = [(– 4) × (– 8)] × (–5)? For any three integers a, b and c, we have a × (b × c) = (a × b) × cMultiplication is associative
DivisionIs [(–10) ÷ 2] ÷ (–5) = (–10) ÷ [2 ÷ (– 5)]? NoDivision is not associative
