In short, in the case of inductive reasoning, the inconclusiveness of the reasoning itself introduces further uncertainty in addition to the original uncertainty of the premises. We rarely have certain knowledge, and a study of logic will not give it to us. Logic is not a

Given a few mathematical statements or facts, we would like to be able to draw some conclusions. For example, if I told you that a particular real-valued function was continuous on the interval \([0,1]\text{,}\) and \(f(0) = -1\) and \(f(1) = 5\text{,}\) can we conclude that there is some point between \([0,1]\) where the graph of the function crosses the \(x\)-axis?

Therefore sign - Wikipedia
https://en.wikipedia.org/wiki/Therefore_signIn logical argument and mathematical proof, the therefore sign, ∴, is generally used before a logical consequence, such as the conclusion of a syllogism.The symbol consists of three dots placed in an upright triangle and is read therefore.While it is not generally used in formal writing, it is used in mathematics and shorthand
