To add and subtract decimals using place value, align the decimal points of the numbers vertically, ensuring that each digit is in the correct place value column (tenths, hundredths, etc.). Use the properties of addition and subtraction, such as the commutative property (changing the order of numbers does not change the sum) and the associative property (changing the grouping of numbers does not change the sum), to simplify calculations. Begin adding or subtracting from the rightmost column (smallest place value) to the left, carrying or borrowing as needed. This method helps maintain accuracy while ensuring that each decimal is treated according to its value.
What else can I help you with?
How can you add decimals without a place-value chart to make sure you adding the same place value?
you can line up the decimals
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 does place value help you subtract decimals?
Place value helps in subtracting decimals by ensuring that digits are aligned according to their respective values—tenths, hundredths, etc. This alignment allows for accurate borrowing and subtraction, similar to whole numbers. By maintaining the correct place values, it becomes easier to manage differences and ensure precision in the result. Ultimately, a clear understanding of place value is essential for performing decimal subtraction correctly.

When converting decimals to fractions is the place value of the number farthest to the right the denominator?
For terminating decimals, yes - the place value of the digit farthest to the right (furthest after the decimal point) is the denominator. Don't forget to simplify the fraction (if possible).
How does understanding place value help you to subtract across zeros?
Understanding place value helps you to subtract across zeros by allowing you to correctly regroup when necessary. When subtracting across zeros, the value of the zero in the minuend (top number) changes based on its position. For example, in 700 - 203, the zero in the hundreds place has a value of 700, not just 0. Understanding this helps you borrow from the hundreds place when subtracting in the ones place, ensuring accurate results.
