What is called in coding?
Coding is a skill where you take instructions (the steps in a task) and translate it into a language the computer understands since computers do not communicate like humans. They communicate in a language called BINARY and it is uses 0’s and 1’s. Coders write the instructions using a programming language.
What does 3 lines mean in maths?
A symbol with three horizontal line segments ( ) resembling the equals sign is used to denote both equality by definition (e.g., means is defined to be equal to ) and congruence (e.g., means 13 divided by 12 leaves a remainder of 1–a fact known to all readers of analog clocks).
What does ≡ mean in math?

In mathematics, the triple bar is sometimes used as a symbol of identity or an equivalence relation (although not the only one; other common choices include ~ and ≈). Particularly, in geometry, it may be used either to show that two figures are congruent or that they are identical.
How did Mark Zuckerberg learn to code?
