Hi, Lisa.

It would appear that you have some wrong check numbers. Without seeing your equations, it is hard for me to troubleshoot. However, I will provide a link to our Pre-Recorded Webinars. There is a fabulous webinar on check numbers that I have found invaluable. Here is the link: http://rightstartmath.com/resources/pre-recorded-webinars/. Go down to the bottom of this link and you will see the webinar on check numbers. I think by viewing it, it will clear up how check numbers work for multiplication and division.

Of course, if you have any further questions, please do not hesitate to repost here or email RightStart Math directly at info@rightstartmath.com.

I am sorry I cannot be of more help. If you would like for me to troubleshoot your equations, feel free to email me the numbers as well as the check numbers. That way I can see exactly what you are doing.

Have a great day!
Rachel
