NCERT Class 7 Mathematics Ganita Prakash: Chapter 2 — Arithmetic Expressions
This chapter introduces students to the concept of simple arithmetic expressions in Mathematics, specifically within the NCERT Class 7 Ganita Prakash textbook. It explains that arithmetic expressions are mathematical phrases like 13 + 2 or 20 – 4, each having a specific value. The chapter demonstrates how to represent these expressions using mathematical symbols and the equality sign (=) to show their values. It also explores how different expressions can yield the same value and how expressions can be compared using inequality signs (<, >). Examples illustrate comparing expressions by considering hypothetical scenarios, making abstract mathematical concepts more relatable for young learners. The chapter aims to build a foundational understanding of algebraic thinking and expression manipulation, crucial for future mathematical studies in the CBSE curriculum.

Frequently asked questions
What is an arithmetic expression?
An arithmetic expression is a mathematical phrase like 13 + 2 or 20 – 4, which uses numbers and mathematical operations.
How do we find the value of an arithmetic expression?
We perform the operations in the expression to find its numerical value. For example, the value of 13 + 2 is 15.
Can different expressions have the same value?
Yes, for example, 10 + 2, 15 – 3, 3 × 4, and 24 ÷ 2 all have the value 12.
How are expressions compared?
Expressions are compared based on their values using the signs =, >, and <.
What does it mean to compare 10 + 2 > 7 + 1?
It means the value of the expression 10 + 2 (which is 12) is greater than the value of the expression 7 + 1 (which is 8).
