One way to help understand place value is by writing numbers in standard form, word form, and expanded form. For example, 9 in 129 has a different value than the 9 in 192. Knowing how to represent numbers in these three different ways will help build place value concepts.
22 wrz 2023 · Standard form is a special way of writing numbers or equations that helps us easily compare and work with them. In standard form, numbers are written as a multiplication of two parts: a number between 1 and 10 and a power of 10. Let’s break it down with some examples.
Standard Form of a Decimal Number. In Britain this is another name for Scientific Notation, where you write down a number this way: In this example, 5326.6 is written as 5.3266 × 10 3, because 5326.6 = 5.3266 × 1000 = 5.3266 × 10 3. In other countries it means "not in expanded form" (see Composing and Decomposing Numbers):

Definition of Standard Form. Standard Form of Numbers: In mathematics, Standard Form is an alternative method for representing numbers that are either excessively vast or small to be expressed in decimal form. It is expressed as \(a \times 10^n\), where \(1 \leq |a| < 10\) and \(n\) is an integer.
Expanded form is a way to express a number as the sum of the place values of its digits. In the expanded form, we break up a number according to the place value of digits and expand it to show the value of each digit. For example, the expanded form of 943 is given below. 943 = 9 hundreds + 4 tens + 3 ones. Expanded Form: 943 = 900 + 40 + 3.
Standard form means expressing numbers using numbers. Word form means expressing numbers by spelling them out in words. Expanded form means expressing according to place value.
