[QUOTstein;4246799]Right. Most modern programming languages would throw an error for doing an implied multiplication.
Come to think of it, which other languages allow something like 5t instead of 5*t?
As far as languages go, I don't think any would interpret 5t ad 5*t .

OP, you should probably decide on the audience you are trying to create the video for. If you are making the video for EE's or physicists, then you are going to have to spend a few months learning all the quantum theory and calculus involved to explore the laws that govern electricity. Also, a...
The obvious part of this discussion as it relates to OP, make sure to look at the input interpretation when you enter formulas. Wolfram clearly displays how it interprets your input, if it does not match your equation then the answer will not match either. logic 101
All of these replies got it right. What helped me when I was learning about inequalities, was to treat it like an equal sign. Then the only additional thing to remember when solving them is to change the direction of the inequality any time you multiply or divide the equation by a negative...
This is a pretty ambiguous question. There are many ways to write an equivalency. Without knowing more specifically what you are trying to do, it would be hard to give you an answer that would work for you.
alternatively, you can explore wolfram and see where that takes you I suppose.
