Unit #2-03

Learning Outcome

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

• create a program that does basic math

Review

• review  basic programs on Micro:bit

Lesson

• the entire point of creating electronic computers was to automate doing math, so let's get the Micro:bit to do simple math for us

  • add

  • subtract

  • multiply

  • divide

  • exponent

• go over ASCII

  • if you happen to know "Unicode" characters, the Micro:bit can only show ASCII characters!

  • basically, no special characters, only the onse you see on the keyboard

Activity

• see "Basic Math" program

  • see MakeCode Micro:bit below: ↓

• go over "types" in TypeScript

  • why we need .toString() 

Daily Assignment

• click on provided link to create a new GitHub repo

  • call the repo: TEJ2O.1-Unit2-03

• create a program that will do the following:

  • that calculates the area and perimeter of a rectangle with dimensions 5 cm & 3 cm, (see screenshot below: ↓)

    • hint: a = l x w or a = 5x3 and p = 2(l + w) or p = 2(5 + 3)

  • REMEMBER: to use everything we learned so far

    • proper style and formatting

    • ENSURE your units are done correctly (space between value and units: 15 cm^2)

Extra

• do the above assignment but in Python
