Test: Operations with integers - Year 7 MCQ

Adding a positive integer (5) and a negative integer (-3) involves subtracting their absolute values and keeping the sign of the larger absolute value, resulting in 5+(−3) = 2.

Multiplying two negative integers results in a positive product, so − 5 × ( − 6 ) = 30.

Dividing two integers with different signs results in a negative quotient, so 21÷(−7) = −3.

Subtracting a negative integer is equivalent to adding its positive counterpart, so 10 − ( − 10 ) = 10 + 10 = 20.

Adding a positive integer (4) and a negative integer (-9) involves subtracting their absolute values and keeping the sign of the larger absolute value, resulting in 4 + (−9) = −5.

Multiplying any integer by zero results in zero, so 0 × ( − 7 ) = 0.

Adding two integers with different signs involves subtracting their absolute values and keeping the sign of the larger absolute value, hence −6 + 8 = 2.

Adding two negative integers involves adding their absolute values and keeping the negative sign, so − 18 + ( − 6 ) = − 24.
