名詞
B1
action
1
process of working with numbers
The action of using numbers to find an answer.
用法パターン：
[someone] does a calculation of [amount]
よくある間違い：
Learners sometimes say *"make the maths"* or *"do the math calculation"* instead of simply *"do a calculation"* or *"do the math"*. Another issue is confusing *calculation* with *counting*: *calculation* usually involves operations like adding, subtracting, multiplying, dividing, or using formulas, not just saying numbers in order.

working out (More informal; especially used in British English for the steps of a math problem.)

number you get after calculating
The number or answer you get after you calculate something.
用法パターン：
according to [someone]'s calculations, [clause]
よくある間違い：
Some learners use *calculation* only for the process and forget it can also mean the final answer. For example, *"According to my result"* is unnatural; it is better to say *"According to my calculations"* when introducing a number or conclusion you reached by calculating.
類義語
result (General word for an outcome; *calculation* stresses that it was found by calculating.)
|
figure (Often used for a single number, especially in financial or statistical contexts.)
対義語
miscalculation (Refers to a calculation that produces a wrong result, the opposite of a correct calculation.)

careful planning for advantage
Careful, planned thinking to get what you want, often in a cold or selfish way.
用法パターン：
[an action] is a matter of [pure] calculation
よくある間違い：
Learners sometimes think this meaning is always neutral, like simple math. In phrases such as *"cold calculation"* or *"political calculation"*, the word often suggests negative ideas like selfishness, manipulation, or a lack of emotion.
類義語
planning (More neutral and positive; does not always suggest cold or selfish motives.)
|
scheming (Stronger negative sense; suggests secret, dishonest, or manipulative planning.)
対義語
impulsiveness (Acting quickly without careful thought or planning, the opposite of calculation.)
