Translation of "Calculators" in Japanese

Can we use Scientific calculators on the analytical chemistry test?

分析化学の試験って関数電卓持ち込み可だっけ？

Make sure you get 2,886, or the calculators are not working.

電卓で確認してください 2,886です 違っていれば電卓が壊れてます

Since I have not had the chance to work with these calculators,

この電卓達とは初仕事ですから

Nowadays, however, calculators can be used freely in school examinations, and already in many schools the only sound to be heard during a math exam is the sound of children tapping on their calculators.

しかし今日では、計算機は学校の試験では自由に使うことが出来るし、数学の試験の時に聞こえる音といえば、子供たちが計算機を叩く音しかしない、という学校も多い。

Pocket calculators are as cheap to buy as a pair of socks, and as essential to thousands of British school children as a pencil and eraser.

ポケットの計算機は靴下と同じくらい安く買え、また、鉛筆や消しゴムと同じくらい、何千人というイギリスの学童にとっては生活に不可欠のものである。
