COMMON QUESTIONS

Using the step-by-step solvers

Can I use negative numbers?

The fraction, percentage, algebra, ratio, and order-of-operations tools accept negative values. Long division currently focuses on nonnegative whole numbers.

Why might a teacher show different steps?

Many problems have more than one valid method. These tools use a consistent, standard method and show an answer check where practical.
