Addition and Subtraction Quizzes for Year 7 Maths

Question 1

When you add or subtract 0 to or from any number, what happens to the number?

Accepted Answer

It stays the same.

Answer

It changes its sign.

Answer

It doubles.

Answer

It halves.

Question 2

How can you use the commutative property of addition to make this calculation easier: 123 + 456?

Accepted Answer

Swap the numbers around, so it becomes 456 + 123.

Answer

Break the numbers into smaller parts and add them separately, like (100 + 20 + 3) + (400 + 50 + 6).

Answer

Add the numbers in order, starting with the smallest one, like 123 + 400 + 56.

Answer

The commutative property only works for multiplication, not addition.

Question 3

Which statement explains why adding or subtracting zero to or from any number results in the same number?

Accepted Answer

Zero is the identity element for both addition and subtraction, leaving any number unchanged when added or subtracted.

Answer

Zero is the smallest natural number, so adding or subtracting it does not affect the value of another number.

Answer

Zero is an even number, so adding or subtracting it maintains the parity (even/odd) of the original number.

Zero is the identity element for addition and subtraction. Explain how this property can be used to simplify calculations. Provide an example to illustrate your answer.

Accepted Answer

Zero can be added or subtracted from any number without changing its value.
