Why can you use addition to check your answer to a subtraction problem?
You can use addition to check your answer to a subtraction problem because subtraction is the inverse operation of addition. If you subtract a number from another and then add that same number back to your result, you should arrive at the original number. This relationship confirms the accuracy of your subtraction result, ensuring that the calculations are correct. If the sum does not match the original number, then there was likely an error in the subtraction process.
What do roman numerals CD stand for?

How can you use a chip model to represent addition and subtraction?
A chip model uses physical or visual representations, such as colored chips, to illustrate addition and subtraction. For addition, you can place chips of one color to represent one number and chips of another color for the second number, then combine them to see the total. For subtraction, you start with a total number of chips and remove a certain number to visualize the result. This hands-on approach helps learners grasp the concepts of these operations effectively.
What is the slide model for subtraction?
The slide model for subtraction is a visual method used to help learners understand the concept of subtraction by representing numbers on a number line. In this model, one number is "slid" backwards from another number to demonstrate the process of taking away or finding the difference. It emphasizes the movement along the number line, allowing students to visualize how subtraction works in a clear and tangible way. This approach can enhance comprehension and retention of subtraction concepts, especially for young learners.
