How do you do subtracting fractions with regrouping?
You do by subtracting one from the previous number and adding 10 to the top number of the digits you are regrouping. Subtract those two digits and you should get your answer.
How is adding decimals similar to adding whole numbers?
Adding whole numbers is the addition of decimals where the decimal part is zero; in both cases the digits are place value aligned meaning that the decimal points, which lies between the units (or ones) and tenths columns, are aligned - in the whole number the decimal point is "hiding" at the end.
What is standard algorithm?
Standard algorithm is when you take two digits or decimals and you put the digit or decimal with the greater value on top and the digit or decimal with the least value on the bottom and you contrast the digits/decimals to see if it greater than, less than,or equal to.
What are terminating decimals?
They are decimal representations of numbers which stop after a finite number of digits (or continue with an infinite string of 0s).
What are the decimals between 0.1 through 011?
There is an infinite amount of decimals between 0.1 and 0.11. Write "0.10", and then add any digit or digits you like - the result will be between those two.
When adding or subtracting decimals how can you be sure to add or subtract only digits that have the same place value?
The simplest way is to line up the numbers so that their decimal points are aligned, and corresponding digits are also aligned according to their place value.
How do you do subtracting fractions with regrouping?
You do by subtracting one from the previous number and adding 10 to the top number of the digits you are regrouping. Subtract those two digits and you should get your answer.
How do you estimate using front-end estimation?
by adding or subtracting the values of the digits in the front place
What must each number have when adding and subtracting scientific numbers?
same number of significant digits
Why is it important to line up the decimal points when adding or subtracting but not when multiplying?
Because when adding or subtracting, the operations must take account of the place values of individual digits in the numbers. When multiplying, only the overall order of magnitudes are relevant for placing the decimal point in the product.
When multiplying decimals count the decimals digits in each?
Yes.
How is adding decimals similar to adding whole numbers?
Adding whole numbers is the addition of decimals where the decimal part is zero; in both cases the digits are place value aligned meaning that the decimal points, which lies between the units (or ones) and tenths columns, are aligned - in the whole number the decimal point is "hiding" at the end.
What determines the number of allowed significant digits when adding or subtracting?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
How do you divide single digits with 3 digits?
by using decimals
What does simplify mean when your adding decimals?
It just means to make sure that you complete the operation and don't have any additional digits when you're done. For example, if you're adding 3.7 and 4.3, you can say the answer is 8, not 8.0.
What is the definition for repeting decimals?
A decimal with a continuously repeating digits or group of digits
When adding or subtracting decimal how can you be sure to add or subtract only digits that have the same place value?
The simplest way is to line up the numbers so that their decimal points are aligned, and corresponding digits are also aligned according to their place value.
