  • 50
  • 35
  • 20
Why are brackets used in mathematical expressions?
  • To make the expression look neat

If Irfan bought a biscuit packet for ₹15 and toor dal for ₹56, and gave ₹100 to the shopkeeper, what expression should be used to calculate the change he will get back?
  • 100 – 15 + 56
  • 100 + (15 + 56)
  • 100 – (15 + 56)
  • 100 × (15 + 56)
What is the change Irfan will get back after buying items worth ₹15 and ₹56 and paying ₹100?
  • ₹141
  • ₹29
  • ₹44
  • ₹85
Explain why evaluating 100 – 15 + 56 without brackets gives an incorrect result.
  • It adds the values before subtracting, leading to a higher result
  • It multiplies the values, leading to a lower result
  • It ignores the order of operations, leading to confusion
  • It uses division instead of addition
What are the terms in the expression 12 + 7?
  • 12 and 7
  • 12 and 19
  • 7 and 19
  • 12 and 14
In the expression 83 – 14, what are the terms after converting subtraction to addition?
  • 83 and –14
  • 83 and 14
  • 14 and –83
  • –83 and –14
Why is subtracting a number the same as adding its inverse?
  • Because the inverse has the opposite sign
  • Because subtraction always increases the value
  • Because addition and subtraction are unrelated
  • Because the inverse is always positive
Which of the following is a single term in an expression?
  • 6 × 5
  • 6 + 5
  • 6 – 5
  • 6 ÷ 5
Given the expression 2 – 10 + 4 × 6, identify all the terms.
  • 2, –10, 4 × 6
  • 2, 10, 4 × 6
  • 2, 10, 24
  • 2, –10, 24
If you replace subtraction by addition of the inverse, does the value of the expression change?
  • No, the value remains the same
  • Yes, the value increases
  • Yes, the value decreases
  • Yes, the value becomes zero
Which of the following is the correct way to write the expression 13 - 2 + 6 as the sum of its terms?
  • 13 + 2 + 6
  • 13 + (-2) + 6
  • 13 - 2 - 6
  • 13 + 2 - 6
What are the terms in the expression 13 - 2 + 6?
  • 13, 2, 6
  • 13, -2, 6
  • 13, 2, -6
  • 13, -2, -6
If you swap the terms in the expression 6 + (-4), what is the result?
  • The sum changes
  • The sum stays the same
  • The sum becomes negative
  • The sum becomes zero
Does changing the order in which the terms are added give different values for the sum when all terms are positive or negative?
  • Yes, the value changes
  • No, the value stays the same
  • Sometimes, depending on the numbers
  • Only when all terms are negative
Why is it important to convert all subtractions in an expression to additions when finding the sum of its terms?
  • It makes the expression longer
  • It helps to identify the terms easily
  • It changes the value of the expression
  • It is not important
What happens to the value of an expression when you swap two terms in it?
  • The value changes
  • The value stays the same
  • The value doubles
  • The value becomes zero
If you add the terms (-7) + 10 + (-11) in different orders, what will be the result?
  • The sum will be different each time
  • The sum will always be -8
  • The sum will always be 0
  • The sum will always be 8
What mathematical property is illustrated when grouping the terms of an expression in any order gives the same value?
  • Distributive property
  • Associative property
  • Commutative property
  • Identity property
Why does grouping the terms of an expression in different ways give the same value, even if some terms are negative?
  • Because negative numbers cannot be grouped
  • Because the associative property applies to both positive and negative numbers
  • Because only positive numbers can be grouped
  • Because the value changes with negative numbers
What is the commutative property of addition?
  • Swapping terms changes the sum
  • Swapping terms does not change the sum
  • Grouping terms changes the sum
  • Addition is not possible without swapping terms
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?
  • Yes, you must start over
  • No, you can just add 9055 to your previous sum
  • Yes, because the order matters
  • No, but you must subtract 9055 from your sum
What is the associative property of addition?
  • Grouping does not change the sum
  • Grouping changes the sum
  • Addition is not associative
  • Only swapping terms is allowed
In the expression 30 + 5 × 4, what should be evaluated first according to the order of operations?
  • 30 + 5
  • 5 × 4
  • 30 × 4
  • 30 + 4
Manasa’s mother says, “Wear your hat and shoes!” Which should Manasa wear first?
  • Hat first, then shoes
  • Shoes first, then hat
  • Either order, it does not matter
  • Neither, she should wear socks first
Placeholder for diagrams showing the evaluation of expressions: "30 + 5 × 4" and "5 × (3 + 2) + 78 + 3"
  • Diagrams show the commutative property
  • Diagrams show the associative property
  • Diagrams show the order of operations in arithmetic expressions
  • Diagrams show multiplication tables
Why does adding the terms of an expression in any order give the same value?
  • Because of the commutative property of addition
  • Because multiplication is always first
  • Because subtraction is not allowed
  • Because division changes the value
If Manasa’s mother says, “Wear your socks and shoes!” what should Manasa do first?
  • Wear shoes first
  • Wear socks first
  • Wear hat first
  • Wear both at the same time
