Because it may have a deciml in it
1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,80,90,100,200
The answer is 20 and they are: 1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,8… and 200 The reason is the expanded form of lets say 11 is 10+1 in which case it is not identical to its standard form. Numbers such as 30 is only 30 and is identical to its standard form.
10 , what are they?
Its when you add all the numbers together
Ironically, the phrase "standard form" is not standard! In the UK, standard form is generally taken to refer to the scientific form. In that case, there are nine numbers: 1 to 9.
A mathematical phrase containing numbers and operations is called an expression. Expressions can be joined together with an equals sign to form an equation.
arabic numbers or decimal numbers
standard form means showing numbers in their normal state. Example- if 3,976 is in expanded form, it would look like this: 3,000 + 900 + 70 + 6 So if a question on a math worksheet asked you what that number would look like in standard from, it would look like this: 3,976- you just took the 0's off of the numbers and put them together.
standard notation: 1,456 expanded notation: 1,000+400+50+6 written: one thousand four hundred fifty six
387.Standard notation is our regular system of writing numbers. So, 387 is already in standard notation! Other kinds of notation include scientific notation and expanded notation.
26 = 64 and 56 = 15625
Take the expanded form for example 900+40+6 and make it 946. Take the first number from each set of numbers and write it and keep going until all of them are complete
