The bewildering question is why always multiplying a negative number by a negative becomes positive?
Why multiplying one negative number by another negative number give a positive result?
Well, the beginning of the calculation here is always from point zero on an imaginary horizontal axis representing infinity and zero in the middle (one side is positive, the other negative)
It is necessary to understand these two points:
The sign of one of the numbers in the equation (positive/negative) indicates the direction of our face as we go.
The other number indicator is the direction of our steps (backward or forwards, keeping the direction of our face according to the signal of the first number)
Annotated examples:
2 x 3 = 6
Three steps twice.
We go on the positive side of the axis, three steps forward twice.
2 x -3 = -6
Three steps twice.
We direct towards the positive side of the axis, three steps back twice (it brings us to 6).
-2X -3 = 6
Three steps twice.
We go towards the negative portion of the axis (because it is -2), 3 steps back twice (so we get to a positive 6).
Here is a linguistic and logical explanation:
"I did not defend you once."
This sentence has two negatives ("no once" x "no")
The result (meaning) is positive: I have always advocated for you.
