CBSE Class 7 Maths Arithmetic Expressions (Class 7 NCERT New) Quiz 6

1. What mathematical property is illustrated when grouping the terms of an expression in any order gives the same value?

A Distributive property B Associative property C Commutative property D Identity property

2. Why does grouping the terms of an expression in different ways give the same value, even if some terms are negative?

A Because negative numbers cannot be grouped B Because the associative property applies to both positive and negative numbers C Because only positive numbers can be grouped D Because the value changes with negative numbers

3. What is the commutative property of addition?

A Swapping terms changes the sum B Swapping terms does not change the sum C Grouping terms changes the sum D Addition is not possible without swapping terms

4. If you add the numbers 1342, 774, 8611, and 1022, but forget to include 9055, do you need to start over to get the correct sum?

A Yes, you must start over B No, you can just add 9055 to your previous sum C Yes, because the order matters D No, but you must subtract 9055 from your sum

5. What is the associative property of addition?

A Grouping does not change the sum B Grouping changes the sum C Addition is not associative D Only swapping terms is allowed

6. In the expression 30 + 5 × 4, what should be evaluated first according to the order of operations?

A 30 + 5 B 5 × 4 C 30 × 4 D 30 + 4

7. Manasa’s mother says, “Wear your hat and shoes!” Which should Manasa wear first?

A Hat first, then shoes B Shoes first, then hat C Either order, it does not matter D Neither, she should wear socks first

8. Placeholder for diagrams showing the evaluation of expressions: "30 + 5 × 4" and "5 × (3 + 2) + 78 + 3"

A Diagrams show the commutative property B Diagrams show the associative property C Diagrams show the order of operations in arithmetic expressions D Diagrams show multiplication tables

9. Why does adding the terms of an expression in any order give the same value?

A Because of the commutative property of addition B Because multiplication is always first C Because subtraction is not allowed D Because division changes the value

10. If Manasa’s mother says, “Wear your socks and shoes!” what should Manasa do first?

A Wear shoes first B Wear socks first C Wear hat first D Wear both at the same time
