Standard Form (Video Tutorial and Quiz)

 In Britain, Standard Form is another name for Scientific Notation. 
In other countries, it just means "not in expanded form."

Standard form is a way of writing down very large or very small numbers easily.

Watch the video by Chegu Selva below for a tutorial on how to answer Standard Form questions from Chapter One Form Four Mathematics.


Now that you've understood the sub-topic of Chapter One, test your understanding by trying out the following questions. Try not to look at the answers until after you're done answering or if you don't know how to do the questions. Good luck!

1.   Express the following in  Standard Form:

      (a)  667500 = ....................

      (b)  5460     = ....................

      (c)  0.0541  = ....................

      (d) 0.00088 = ...................

2.   Change the following into normal numbers:
      
      (a)  5.5 x 10-7     = ....................
      (b) 1.76 x 105     = ....................
      (c)  3.955 x 10-2 = ....................

Answers: 1 (a)  6.675 x 10 5(b)  5.46 x 10 3 (c)  5.41 x 10 -2  (d)  8.8 x 10 -4
