You could divide the answer into the larger number of the problem. The answer should be the remaining number (multiplicand).
you just mult
multiplication is the Inverse operationof division so it could be used to check my work
40/5=8
You can do reverse operation to check. If you checked it and it is not the answer you got, try the problem and recheck it to see if your right.
It affects because if you want to solve a multiplication problem you can use it or also to check your division problem
Multiply the answer to the problem by the number that you are dividing by. (e.g. 18/2=9 Check it with 9*2=18)
then do the oppsite.Multiply.

Take the answer of the division problem and multiply it by one of the numbers. It should equal the OTHER number. a/b = c c * b = a OR c * a = b

just kidding guys :P
To check the answer to a division question, multply the divisor (the number that is being divided into the dividend) and the quotient (the answer). If there is a remainder, add the remainder to the answer. If the number matches the dividend, your answer to the division problem is correct.
