Welcome to this deck on standard form. Standard form is a convenient way to write very large or very small numbers, which you'll often see in science. In this deck, you'll learn how to write numbers in standard form, convert them back to ordinary numbers, and perform all four main calculations: adding, subtracting, multiplying, and dividing.
Lesson#2
So, what is standard form? It's a number written in a specific format: a number 'A', multiplied by 10 raised to a power, 'n'. This looks like A times 10 to the power of n.
Quiz#3
What is the general format for a number in standard form?
A times 10 to the power of n
Lesson#4
There's a very important rule for the first number, 'A'. It must be greater than or equal to 1, but less than 10. This means it can be 1, but it can't be 10. For example, it could be 3.45, or 9.9, or just 1.
