Double Negation refers to these composed by using two negatives to indicate a positive meaning, but with a stronger mood or tone than an equivalent simple positive statement.
*Using two negative adverbs
The simple way to form a double negation is using two negative adverbs together, but the meaning of the sentence is definitely positive.
Subject + 不得不 + Verb / Adjective
Subject + 不是 + 不 / 没 + Verb / Adjective
Subject + 不 + 会 / 能 / 可能 + 不 / 没 + Verb / Adjective

*Using negation with numeral word together

一 + Measure Word（+ Noun）+ 也 (都) / 也没（不）+ Verb / Adjective
