Checkpoint: multiplying, sharing and zero

What is (−5) × 3, and why?

• −8, because 5 and 3 make 8
• 15, because two of the numbers are odd
• −15, because it is −5 repeated three times

The −4 times table reads −12, −8, −4, 0. The count drops 3, 2, 1, 0. What comes next?

• −4, because the pattern turns round
• 4
• 0, because the table stops at zero

What is (−3) + (−4), and what is (−3) × (−4)?

• Both come to 12
• The sum is −7 and the product is −12
• The sum is −7 and the product is 12

What is 20 ÷ (−5)?

• 4
• There is no answer. You cannot share into a group below zero
• −4

Which of these has no answer at all?

• 7 ÷ 0
• 0 × 7
• 0 ÷ 7
