What is a problem string?

A Problem String is a series of related problems purposefully sequenced to help students construct mathematical relationships so that powerful strategies become their natural instincts. … In this mini-lesson structure, teachers and students interact to construct important mathematical strategies, models, and concepts.

How do you multiply a long number in Java?

long value = 1024 * 1024 * 1024 * 80; multiplies some integers together, converts it to a long and then assigns the result to a variable. The actual multiplication will be done by javac rather than when it runs. Since int is 32 bits, the value is wrapped and results in a zero.
