GRADE 8 Mathematics – Integers Quiz

In integers, the smaller the number, the further it is to the left on the number line. Therefore, -5 is the smallest number among the choices.

The opposite of a negative number is the positive version of the same number. Therefore, the opposite of -12 is 12.

Integers are whole numbers and their opposites. 2/3 is not a whole number or its opposite, hence not an integer.

Adding a negative and a positive integer results in subtraction. Therefore, -6 + 4 = -2.

When adding two negative integers, you add the absolute values and keep the negative sign. Therefore, -9 + (-3) = -12.

A multiple of 5 is any number that can be divided by 5 without leaving a remainder. -10 is a multiple of 5.

In integers, the smaller the number, the further it is to the left on the number line. Therefore, -2 is greater than -5.

When multiplying integers with different signs, the result is negative. Therefore, -4 * 6 = -24.

Natural numbers are whole numbers greater than 0. 3 is a natural number as it is a positive whole number.

When dividing integers with different signs, the result is negative. Therefore, 15 / -3 = -5.

3.14 is a decimal number, not an integer. Integers are whole numbers, either positive, negative, or zero.

Zero is the only integer that is neither positive nor negative. It lies at the center of the number line.

When you add two negative integers, the result will always be negative. The negative sign is retained.

The opposite of a negative number is the same number with the sign changed. So, the opposite of -15 is 15.

Positive integers are numbers greater than zero. In this case, 3 is a positive integer.

When you multiply two negative integers, the result will always be positive. The negative signs cancel out.

-1 is a negative integer because it is less than zero. Negative integers are represented with a minus sign.

When you add a negative number and a positive number, you subtract the smaller absolute value from the larger and keep the sign of the larger.

Even integers are numbers that are exactly divisible by 2. In this case, -6 is an even integer.

When you multiply two negative integers, the result is always positive. Therefore, -4 x -7 = 28.

Non-negative integers are either positive numbers or zero. In this case, 5 is a non-negative integer.

The opposite of zero is zero itself. Zero has no sign since it is neither positive nor negative.

When you subtract a negative number from a positive number, the result will always be positive. The two negatives cancel out.

Multiples of a number are obtained by multiplying that number by integers. In this case, 8 is a multiple of 4.

When adding integers, remember to consider the signs. In this case, -2 + 6 + (-1) = 3.

Rational numbers are numbers that can be expressed as a ratio of integers. In this case, 1/3 is a rational number.

Any non-zero integer divided by itself will always result in 1. This is a fundamental property of division.

Odd integers are numbers that are not divisible by 2. In this case, -5 is an odd integer.

The opposite of a negative number is the same number with the sign changed. So, the opposite of -1 is 1.

When you multiply a negative number and a positive number, the result is always negative. -3 x 5 = -15.

A prime number is a number greater than 1 that has no positive divisors other than 1 and itself. In this case, 7 is a prime number.

When you add a negative number and a positive number, you subtract the smaller absolute value from the larger and keep the sign of the larger.
