In this post, we are going to learn how to round and use estimation in subtraction problems. Mastering this skill is helpful in verifying that an exact answer is of the correct order of magnitude and also in determining whether an answer is reasonable or not. Round and Estimating Subtraction Problems in Tens Round the […]
