What Is the Math by Hand Application?

The Math by Hand application familiarizes you with mathematical
algorithms for addition, subtraction, multiplication, and division. For each
of these, three dif ferent modes are available:

Step-By-Step mode shows the problem worked out one step at a

•

time, emphasizing place value in the base-ten system for each
algorithm.

Fast Math mode shows the problem worked out in an animated

•

sequence that is similar to how you would solve the problem on
paper.

Missing Pieces mode is a quiz that presents solved problems with

•

blank place values. You supply these place values to complete the
algorithm.

The Math by Hand application is a concept application that TI wants to
share with our customers, educators, and s tudents before the product
definition and testing are complete. I t is an alpha software version, and as
such, it may contain imperfections, or t he c oding may be incomplete.

TI invites your feedback concerning t he functionality and educational
value of the Math by Hand application. Please send your comments and
