Unit1-04: Basic Math Operators

Learning Outcome

At the end of this lesson, you will be able to :

A1.4 demonstrate the ability to use Boolean operators (e.g., AND, OR, NOT), comparison operators (i.e., equal to, not equal to, greater than, less than, greater than or equal to, less than or equal to), arithmetic operators (e.g., addition, subtraction, multiplication, division, exponentiation, parentheses), and order of operations correctly in computer programs;
write a program that uses basic math operators

With a pencil and paper, answer the following questions:

For ICS3U Only:

Note: Use Programiz (an online Python interpreter) to run code and check your answers!
read "Python Operators" and watch the video within

watch "Basic Math Operators in Python"
- the entire point of creating electronic computers was to automate doing math
- add
- subtract
- multiply
- divide
- exponent
read "Python String Formatting"
- use: print("STRING EXPRESSION = {}".format(CALULATION)), where EXPRESSION is the string you want to write and CALCULATION is what you want to calculate
- if I want to print "2 + 3 = 5", I would type:
  - print ("2 + 3 = {}". format (2+3))
- if I wanted to print the number 3.1415926 rounded to 2 decimal places, I would type:
  - print ("{:.2f}.format(3.1415926))
  - this would output: 3.14
watch "Area & Perimeter of a Rectangle in Python"
- calculate and display the area and perimeter of a rectangle that has a length of 5cm and a width of 3cm.
