take one number from another
To take one number or amount away from another number or amount.
用法パターン：
to subtract [amount] from [amount]
よくある間違い：
Learners often say *"subtract 10 to 3"* instead of *"subtract 3 from 10"*. Remember that in English we normally say *"subtract [smaller number] from [bigger number]"*. Another mistake is using "minus" as a verb: instead of *"minus 5 from 10"*, use *"subtract 5 from 10"* or *"10 minus 5"* as a sentence pattern.

Learners sometimes try to use this meaning directly with numbers, as in *"The noise subtracts 5 points"*. For numbers, it is clearer to use the basic math sense (*"subtract 5 points from his score"*). Use *"subtract from"* + a general noun (enjoyment, experience, value, effect) when talking about quality or impression.
