The games primarily focused on mathematics, later expanding into language arts and science, and spawned an animated children's television series in 1999 called Blaster's Universe.

Take half of the neighbor, then, if the current digit is odd, add 5. Example: 42×5=210 Half of 2's neighbor, the trailing zero, is 0. Half of 4's neighbor is 1. Half of the leading zero's neighbor is 2. 43×5 = 215 Half of 3's neighbor is 0, plus 5 because 3 is odd, is 5. Half of 4's neighbor is 1. Half of the leading zero's neighbor is 2. 93 ...
The Karatsuba algorithm was the first multiplication algorithm asymptotically faster than the quadratic "grade school" algorithm. The Toom–Cook algorithm (1963) is a faster generalization of Karatsuba's method, and the Schönhage–Strassen algorithm (1971) is even faster, for sufficiently large n .

Games are played by a single contestant, who attempts to answer questions correctly plus one final fifth grade bonus question with the assistance of one of three fifth grade classmates (instead of five on the network version), who vary each week.
