AND ACCURATE SOLUTIONS GRADED A+
⩥ describe an algorithm using flow charts. Answer: Don't stress! Flow
charts are almost exactly like normal instructions, but you have to phrase
them in ways or depict them in ways that suggest how a computer may
process the instructions.
⩥ Binary system. Answer: The binary number system is base 2, using
only bits 0 and 1.
⩥ Data Types. Answer: A way to encode some type of data some
computers can manipulate it- using binary numbers.
⩥ decimal system. Answer: system of numbers based on 10. basically
each numeric position increases by a power of 10.
⩥ Hexadecimal Number System. Answer: a base-16 system, consisting

⩥ str. Answer: A Python data type that holds a string of characters.
⩥ Expressions. Answer: expressions always evaluate to a value. pieces
of code that produce a value. Computers take in expressions and convert
them into data the computer can understand,(binary). Allows humans to
use less binary and understand code easier. The literal expression 123 is
evaluated by Python to the int value one-hundred and twenty-three,
which is represented in Binary by the computer as 1110112. An
expression is instructions for the computer to follow. The result is a
value.
⩥ operators. Answer: Operators are symbols such as +, -, × and / that
represent operations such as addition, subtraction, multiplication, and
division. Operators operate on operands.
⩥ compound expressions. Answer: Compound expressions are
expressions composed of sub-expressions.A compound expression is a
sequence of instructions for the computer to follow. The result is a value.
Compound expressions are always evaluated according to the order of
operations.
