Come explore the four main operations (+, -, x, /) across whole numbers, fractions, decimals, and negative numbers and learn where the algorithms, tips, tricks, and mathematical “magic” of operations comes from (hint: it’s not magic at all, just a simplification of steps over thousands of years).

In this course you’ll learn about the historical aspects of numbers and operations with numbers and be taken, step-by-step, through why various ways of solving math operations work the way they do.

Topics include: 

• • Addition, Subtraction, Multiplication and Division with:
    
    • Whole Numbers, Fractions, Decimals, and Negative Numbers
  • How the following “tricks” work:
    
    • Flip and multiply
    • “Carrying” and “Borrowing”
    • Why common denominators for fraction + and -, but not x and /
    • Long Division
    • Two negatives make a positive
  • Order of Operations
  • Rounding
  • The Power of Zero and One
  • Multiples and Factors
  • Significant Digits
  • and more…
