Integers MCQ Test — Class 6 ICSE

Solution:

Integers are whole numbers that can be positive, negative, or zero.

5 is a positive integer.

0 is neither positive nor negative.

1/2 is a fraction, not an integer.

-3 is a negative integer. — -3 < 0

Solution:

On a number line, positive numbers are to the right of 0 and negative numbers are to the left of 0.

-2 is a negative number, so it lies to the left of 0.

Solution:

'Below zero' indicates a temperature less than 0.

8 degrees below zero is written as -8. — 8 below 0 = -8

Solution:

Place the numbers on a number line: -3 is farthest left, then -1, then 0, then 2.

So the correct ascending order is: -3, -1, 0, 2.

Solution:

The absolute value of a number is its distance from 0 on the number line, ignoring direction.

|-6| = 6 because -6 is 6 units away from 0. — |-6| = 6

Solution:

Both numbers are negative, so we add their absolute values.

3 + 4 = 7 — 3 + 4 = 7

Since both are negative, the result is negative. — (-3) + (-4) = -7

Solution:

When adding a positive and a negative number, subtract the smaller absolute value from the larger.

5 - 2 = 3 — 5 + (-2) = 5 - 2 = 3

Since 5 has the greater absolute value and is positive, the result is positive.

Solution:

Zero (0) is the integer that is neither positive nor negative.

It is the dividing point between positive and negative integers on the number line.

Solution:

The successor of an integer n is n + 1.

Successor of -5 = -5 + 1 = -4. — -5 + 1 = -4

Solution:

The predecessor of an integer n is n - 1.

Predecessor of 0 = 0 - 1 = -1. — 0 - 1 = -1
