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.

I can help you solve problems involving fractions, decimals, ratios, and algebra. I can teach you how to do math faster, and even in your head. I can teach math definitions, and help you study, if necessary. Please do not ask any graphing, trigonometry, or calculus questions. Try to work through homework questions before asking for assistance.

Experience

I routinely process numbers of all kinds in my head, without need of a calculator.

Education/Credentials I was an A math student while in high school.
