You don’t need to know how to actually do this multiplication to use the mental math trick we’re about to uncover, you just need to know that: (a+b)^2 = (a+b) x (a+b) =a^2 + 2ab+b^2 OK, great…but what does this have to do with squaring numbers in your head? How...
Once Youtube Kids is installed on your FireStick. Open it, and you will be asked to 2 choices. I’M A KID, and I’M A PARENT. If you are a parent, hit the I’M A PARENT button. Next, the app verifies your age and, after signing in, asks you to solve a multiplication prob...
If an individual project fails, “no Biggie” it’s a prototype for the next project. If a project is nolonger needed being small it can just be pulled/replaced. You have to “trim the cruft” and tidy up harder than you write new code. As for testing… Well the more you do the ...
Then, after starting to teach memory techniques, I used these skills to help me learn how to run this blog, my Youtube channel and podcast. I’ve come to master a very complicated set of tasks that I would not be able to handle without proper mnemonics. I’ve also studied hundreds of...
In R, how do I code "only show the first 2 words" of an output? Seeking help for using filter and mutate command to break down a current variable into separate variables Rstudio crashs on macOS with the X11 cairo type window Principal Components Analysis (PCA) Error: Long vecto...
This weekend we visited four different libraries and the library with the best Halloween decorations was Waverley Library!! ️🦇🎃🐈⬛ Otto had his very first Judo grading!! He's so proud of his new belt Otto trying out some more paper
Might be able to mask that away with some clever use of sign() and multiplication. Is that correct? The inner loop would be slower, but all the work to get there should be much faster and simpler. But, I'm not confident in my math. This would limit the size of our RLE convolution...
So if you would like to do the math and it's not hard math, it's linear algebra is just multiplication, addition, exponents, square roots, that's it. It's not hard math, it's just done with giant linear algebra matrices. And so if you want to get into that, have at it. You...
This is just multiplication and division. The “!” is thefactorialsymbol. That’s just a special way of multiplying numbers. To get a factorial, multiply the number by each number below it until you get to 1. For example: 4! = 4 x 3 x 2 x 1 = 24 2! = 2 x 1 = 2 Goo...
Python's.format() function is a flexible way to format strings; it lets you dynamically insert variables into strings without changing their original data types. Example - 4: Using f-stringOutput: <class 'int'> <class 'str'> Explanation: An integer variable called n is initialized with ...
