Multiplication...

$n(x) - n = n(x - 1)$

Example:

$6(7) - 6 = 6(6) = 36$

Comparing it with normal method:

$6(7) = 42 - 6 = 36$

Therefore:

$n(x) - n = n(x - 1)$

$n(x) + n = n(x + 1)$

Example:

$6(7) + 6 = 6(8) = 48$

Comparing it with normal method:

$6(7) = 42 + 6 = 48$

Therefore:

$n(x) + n = n(x + 1)$

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

I don't understand the specialty of this and the triangle note. Its stuff they teach in Pre-Algebra courses in 5th grade(atleast I learnt it in 5th grade). This comment may seem offensive but I hate redundancy, so I am posting this :)

Look, I found this out.

And I just want to show it...
