Class 7 Maths Part 1 Chapter 2, Arithmetic Expressions, teaches how to read, write, compare and evaluate multi-step mathematical expressions using terms, brackets, the distributive property and commutative/associative grouping without rote confusion.
What Class 7 Mathematics Chapter 2 Covers
2.1–2.2 Simple & Complex Expressions, Brackets and Terms defines an arithmetic expression and its value, shows how decomposing an expression into signed terms separated by ‘+’ signs prevents order-of-operations mistakes, and uses brackets to group operations.
Swapping, Grouping & Removing Brackets I–II demonstrates that terms can be swapped (commutativity) and grouped (associativity) in any order, how a minus sign before a bracket flips the signs of terms inside: $a – (b + c) = a – b – c$ and $a – (b – c) = a – b + c$, and how multiplication distributes over addition and subtraction: $a \times (b + c) = a \times b + a \times c$.

FAQ
What happens when you remove brackets preceded by a minus sign?
When removing brackets preceded by a subtraction (minus) sign, the sign of every term inside the brackets reverses: $a – (b + c) = a – b – c$ and $a – (b – c) = a – b + c$.
What is the distributive property of multiplication over addition?
Multiplying a number by a sum gives the same value as multiplying the number by each term separately and adding the products: $a \times (b + c) = (a \times b) + (a \times c)$.
