๐ Topic Summary
Checking division answers is like doing the opposite of dividing to see if you get back to where you started. In simple terms, if you divide 10 by 2 and get 5, you can check your answer by multiplying 5 by 2. If you get 10, you know your division was correct! This method uses multiplication to verify the accuracy of division.
When checking division with remainders, you multiply the quotient (the answer) by the divisor (the number you divided by) and then add the remainder. If the result equals the dividend (the number you started with), your answer is correct! This ensures that every part of the division problem is accounted for.
