Tool to check an equality between 2 mathematical expressions (written in different forms, factored, expanded etc.). Checker with or without unknown values / variables.
We can prove lines and angles equal if we can show they are corresponding parts of congruent triangles, We find it convenient to present these proofs in double-column form with statements in the left columnand the reason for each statement in the right.

13 Ιουν 2020 · By the distributive law, $(x + 1)(x - 1) = x^2 - 1$. Set $x = -1$ and observe that the left hand side is zero, so the right hand side is zero, so $x^2 = 1$. It's arguable whether the assumptions I use there are any more or less obvious than the conclusion.
17 Απρ 2022 · First, multiply both sides of the inequality by xy, which is a positive real number since x > 0 and y > 0. Then, subtract 2xy from both sides of this inequality and finally, factor the left side of the resulting inequality. Explain why the last inequality you obtained leads to a contradiction.
20 Ιαν 2024 · 1 + 1 = 2. 2 + 2 = 4. 2000 + 24 = 2024. At first glance, they are just simple additions that even a 6 year-old kid would be able to compute. Now what if I told you that mathematicians in the past…
Mathematical induction is a method of mathematical proof typically used to establish a given statement for all natural numbers. It is done in two steps. The first step, known as the base case, is to prove the given statement for the first natural number.
