The value of the position of a digit in a number.

expanded notation

Expanded notation is when you write a number to show each digit's value. For example, you would write 5329 as 5000+300+20+9.

An example of how you use expanded notation in addition is 3 x 100 + 9 x 10 + 3. The standard notation for the previous example is 393. Expanded notation is shown by showing the sum of each digit multiplied by its place value (hundreds, thousands, tens, and so forth).

Expanded notation is writing the number to show the value of each digit. 180 = (1 x 100) + (8 x 10) + (0 x 1)

Expanded notation means taking each digit and multiplying it by its place in the number (ones place, tens place, hundreds place, etc.). So, 308,004 in expanded notation would be:(3 x 100,000) + (0 x 10,000) + (8 x 1,000) + (0 x 100) + (0 x 10) + (4 x 1)Which could be simplified to:(3 x 100,000) + (8 x 1,000) + (4 x 1)

In expanded form it is 20+5.The expanded for is a nice way to break up a number to show how much each digit represents. In the example above it shows we have 2 tens and 5 ones.

A 3 or 4 digit number.

Based on your abbreviation for mathematics, I guess you are American. American usage of Standard Notation is to mean ordinary numbers - ie a number written normally. It is the opposite of expanded notation whereby the number is written as the sum of its digits each multiplied by its place value column. For example 123.4 is standard notation; in expanded notation it would be written as 100 + 20 + 3 + 0.4 In the UK, Standard Notation is used to mean scientific notation (or standard index notation) which is a number with one non-zero digit before a decimal point multiplied by a power of 10. It is a way of writing ordinary numbers, especially very big or little ones. For example 123.4 is an ordinary number which is 1.234 × 10² in standard notation. By multiplying out the standard notation the ordinary number is retrieved: 1.234 × 10² = 1.234 × 100 = 123.4

Expanded Notation is the technique of writing out a number by place value sections. A place value section is how much each digit is worth. For example, in 4.79, the place value sections are- Four stands for 4, seven stands for seven tenths, and nine stands for nine hundredths. Expanded notation form would be 4 + .7 + .09. It is a form of writing it out by place value sections.

What is multiplying 2-Digit by 2-Digit numbers

No. It depends on how good you are at arithmetic.

Steps in scientific notation 1. Identify the location of the decimal point. 2. Move the decimal point, stop moving after 1st none zero digit, stop moving the non zero digit, 3. Identify the multiplying factor 4. Identify the exponent

15729=10000+5000+700+20+9 or the highest digit plus next highest plus nexthighest and so on

They are the same because they are both multiplication. They also can be the same if the two digit number times by the one digit number equals a three digit number. They are different because the 3 digits number will obviously produce a higher product.

By writing each digit as its value and summing them: 2,096 = (2 x 1000) + (0 x 100) + (9 x 10) + (6 x 1)

Multiplication in general is important; not just 2-digit numbers.
