### In the lessons

In maths lessons pupils use calculators for big or hard sums and to check answers, but must also learn mental and written methods; in some tests calculators are not allowed. A sensible estimate first helps you spot when you pressed a wrong key. Phrases: «calculator allowed», «use a calculator to check».

Countable. Spelled «calcul-ator» (ends in -or). Verb: calculate; noun: calculation. Trap: a calculator only gives the right answer if you type the right numbers and the right operation, so think about whether the answer makes sense.
