Last year we studied what scientific notation is. Here it´s the definition and some examples.
And now a TEST.
Adding and subtracting numbers in scientific notation
Watch the explanation.
So, when adding or subtracting in scientific notation, you must express the numbers as the same power of 10. This will often involve changing the decimal place of the coefficient.
For some exercises, try sections G and H on this page. The answers are at the end of that page.
Multiplying and dividing numbers in scientific notation
It´s so much easier. Just multiply or divide the coefficients and the powers of 10. Try the exercises at the end of these pages: multiplication, division.
