The title sounds crazy, right? You have to learn a little math. However, to understand the meaning of an equation like this, we need to analyze how the teachings of the Torah work.
Generally, when you have a question about a topic and then find the answer, the question becomes irrelevant. There is no longer a question, only the answer remains, and you can continue exploring the topic.
But in the Torah it is not so. A question in the Torah is as much Torah as the answer. That is to say, if the Torah is true and eternal, every part of it, even the questions, must be true, because otherwise we would end up with a "half-true" Torah, which makes no sense.
Therefore, we understand that even after finding the answer to a question, the question remains valid. Now our equation makes sense: -1 is a question. 1 is the answer. 0 is the resolution of a conflict. Let's look at the equation: "question" + "answer" = "resolution" and "question." The question remains a question according to the Torah.
In this week's section, we read God's answer to Moses' question, "Why have you dealt so badly with these people?" God essentially says that everything will be alright and that He will bring His people out of Egypt with great miracles and wonders. However, even with this answer, the question remains valid.
We learn from this that in the life of a Jew there are two "movements": on the one hand, absolute faith in Divine goodness and that everything will be alright. God is in control of everything; on the other hand, one must question things and ask God to be good to us in a revealed and immediate way. This is not a contradiction, but rather expressions of different qualities of the Jewish soul (faith and intellect).
Although God has His own timing for bringing about the Final Redemption, it is our right (and duty) to demand that it be swift in our day. We want Messiah NOW!
