How can i use place value and properties to add and subtract decimals?
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.

Why must you line up the decimal points when adding and subtracting fractions?

How does understanding place value help you subtract across zeros?
Understanding place value is crucial when subtracting across zeros because it allows you to regroup or borrow correctly from higher place values. For example, if you need to subtract a larger digit from a smaller one in the ones place, knowing that you can borrow from the tens place helps you convert the zero into a more manageable number. This systematic approach ensures accuracy and clarity in the subtraction process. Overall, recognizing the value of each digit facilitates smoother calculations, especially when zeros are involved.

How does a place value chart help you add and subtract decimals?
Place Value Charts help you because they put the decimal in the right place.
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.
