5. What languages (notations) are
Formal notational systems for expressing problem solving abstractions in human and machine readable form. or
Extended algebraic notations.

6. Here is an algorithm for outputting Y spaces:
Machine Assembler High Level Language
COUT EQU $FDED; space := " ";
F SPACE BEQ DONE WHILE Y > 0
A9 A0 LDA #$A DO
20 ED FD NXSPC JSR COUT WriteChar(space);
DEY DEC (Y);
D0 FA BNE NXSPC END;
DONE RTS

7. NOTES
1. Even when writing assembler, one must know intimate details of the machine's hardware and/or firmware.
2. High level languages, especially if ISO standardized, are machine independent.
3. Machine readability can be precisely defined, whereas human readability is an imprecise idea.

8. Why Study Programming Notations?

9. To better express abstractions of problem solutions

10. To better express abstractions of problem solutions
To be able to pick appropriate tools for a task

11. To better express abstractions of problem solutions
To be able to pick appropriate tools for a task
To learn how to learn the use of new tools

12. To better express abstractions of problem solutions
To be able to pick appropriate tools for a task
To learn how to learn the use of new tools
To understand implementation issues

13. To better express abstractions of problem solutions
To be able to pick appropriate tools for a task
To learn how to learn the use of new tools
To understand implementation issues
To know how and why notations are designed
To better use the tools we do understand
