Question
7.2984 - 401

Hello, Gishie.

7.2984 - 401 = -393.7016.

To subtract a larger number from a smaller one, first subtract the smaller number from the larger number. In this case, subtract 7.2984 from 401, which gives you 393.7016. This number needs to be made negative, though, since this is the result when a larger number is subtracted from a smaller one.

Hope this helps.

Regards,
John
