Sample questions

Q1
hard
Starting at $-2$ on the number line, which move lands on $-9$?
  1. A $7$ steps to the right
  2. B $11$ steps to the left
  3. C $7$ steps to the left
  4. D $9$ steps to the left
Show answer and explanation

Correct answer: C - $7$ steps to the left

Going from $-2$ to $-9$ means decreasing by $7$, which is $7$ steps left. Moving right would increase the value, and $9$ steps left would reach $-11$.
Q2
medium
What is $(-12) + 12$?
  1. A $-24$
  2. B $0$
  3. C $12$
  4. D $24$
Show answer and explanation

Correct answer: B - $0$

An integer and its opposite cancel exactly, so the sum is $0$. Answering $24$ ignores the minus sign and adds the sizes.
Q3
medium
A shopkeeper makes a profit of ₹$300$ on Monday and a loss of ₹$450$ on Tuesday. What is the overall result?
  1. A A profit of ₹$150$
  2. B A loss of ₹$150$
  3. C A profit of ₹$750$
  4. D A loss of ₹$750$
Show answer and explanation

Correct answer: B - A loss of ₹$150$

Writing profit as $+300$ and loss as $-450$ gives $300 + (-450) = -150$, a loss of ₹$150$. Adding the amounts without signs would wrongly give ₹$750$.
Q4
medium
A thermometer reads $0^\circ$C. What does this mean?
  1. A The temperature is at the freezing point of water, the chosen zero of the scale
  2. B The thermometer is broken
  3. C There is no temperature
  4. D It is the coldest possible temperature
Show answer and explanation

Correct answer: A - The temperature is at the freezing point of water, the chosen zero of the scale

The Celsius scale sets zero at the freezing point of water, so $0^\circ$C is a real temperature. Colder readings exist below it, shown as negative numbers.
Q5
easy
Subtracting an integer is the same as
  1. A multiplying by $-1$ and then subtracting
  2. B ignoring its sign
  3. C adding its opposite
  4. D adding the same integer
Show answer and explanation

Correct answer: C - adding its opposite

The rule $a - b = a + (-b)$ turns every subtraction into an addition. Adding the same integer would give a different answer, and signs may never simply be ignored.
Q6
easy
Which integer comes immediately after $-5$?
  1. A $-4$
  2. B $4$
  3. C $5$
  4. D $-6$
Show answer and explanation

Correct answer: A - $-4$

Moving one step right from $-5$ gives $-4$, which is greater. Moving left would give $-6$, which comes before rather than after.
