How do you estimate decimal sums and differences?
The basic idea is the same as when you estimate sums and differences of larger numbers (which may or may not be integers). You round the numbers to one or two decimal digits, then add them up.
What are two ways in which whole numbers and decimal numbers are different?
Whole numbers are a proper subset of decimal numbers. All whole numbers are decimal numbers but not all decimal numbers are whole numbers.
Why might you need to be able to estimate an irrational numbers?
Because rational numbers aren't able to be notated precisely in decimal form. They don't stop.
How can you estimate the sum of a decimal and a fraction?
The simplest is to convert both into the same form. Whether you choose to go for two decimal numbers or two fractions is a matter of personal preference. Add the two parts together and you have your estimate.
Why do you estimate when adding or subtracting decimal numbers?
In more than 40 years as a mathematician, I have never needed to do so.

How many numbers are in a decimal?

What are numbers expressed in the decimal system?
All real numbers can be represented in the decimal system. Complex numbers can be represented by a pair of numbers in the decimal system.
Why not all the decimal numbers can be written as rational numbers?
Decimal numbers that can be expressed as fractions are rational but decimal numbers that can't be expressed as factions are irrational
What kind of decimal numbers are irrational numbers?
They are the decimal numbers that can't be expressed as fractions.
Are natural numbers are decimal numbers?
Almost all numbers that we use in daily life are decimal numbers. The place value of each digit is ten times the place value of the digit to its right. And that is all that is required of decimal numbers. A decimal point is not necessary.
