What operations with integers means

You learn how to work with positive and negative whole numbers in calculations. This helps you handle number problems in algebra, money, and everyday situations where gains and losses are shown with signs.

What you will practise

  • Add integers using positive and negative signs correctly
  • Subtract a negative number by changing it to addition
  • Multiply two integers and choose the correct sign
  • Divide integers and keep the right sign
  • Find answers from short number sentences

Before you start

You should already be comfortable with whole numbers, the number line, and the meanings of plus and minus signs. You also need to know basic multiplication and division facts.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

Work out (−8) + 5.

  • −13
  • −3
  • 3
  • 13
Answer: −3

Working: Start at −8 and move 5 to the right: −8 + 5 = −3.

Common mistakes to avoid

  • Treating a negative plus a positive as always negative. Check the signs and move along the number line carefully.
  • Forgetting that subtracting a negative becomes addition. Rewrite the expression before you calculate.
  • Using the wrong sign after multiplication or division. Remember: same signs give a positive answer.
  • Missing a zero or sign in the final answer. Read your working again before you stop.
