Standard form
There are many different standard forms: standard forms of numbers, of linear equations, of circles, etc. The standard form of numbers simplifies working with very large and very small numbers.
In standard form, there is no slope for three numbers.
The notation 2.19e10 represents the number 2.19 multiplied by 10 raised to the power of 10. In standard form, this is equal to 21,900,000,000. This notation is commonly used in scientific and mathematical contexts to express large numbers in a more compact form.
Do nothing! Standard form and scientific notation are the same.
