Symbolab is an answer engine [1] that provides step-by-step solutions to mathematical problems in a range of subjects. [2] It was originally developed by Israeli start-up company EqsQuest Ltd., under whom it was released for public use in 2011.
The Diabolical cube is a puzzle of six polycubes that can be assembled together to form a single 3×3×3 cube. Eye Level also makes use of the Thinking Cube (once students are in levels 30-32 of Basic Thinking Math or levels 29-32 of Critical Thinking Math), as one of its Teaching Tools, similar to the Soma cube.
So only G=8 is possible and with 2+8=10+U, U=0. The use of modular arithmetic often helps. For example, use of mod-10 arithmetic allows the columns of an addition problem to be treated as simultaneous equations , while the use of mod-2 arithmetic allows inferences based on the parity of the variables.
A mathematical exercise is a routine application of algebra or other mathematics to a stated challenge. Mathematics teachers assign mathematical exercises to develop the skills of their students. Early exercises deal with addition, subtraction, multiplication, and division of integers.

The Stanford Research Institute Problem Solver, known by its acronym STRIPS, is an automated planner developed by Richard Fikes and Nils Nilsson in 1971 at SRI International. [1] The same name was later used to refer to the formal language of the inputs to this planner.

The possible row (or column) permutations form a group isomorphic to S 3 ≀ S 3 of order 3! 4 = 1,296. [4] The whole rearrangement group is formed by letting the transposition operation (isomorphic to C 2) act on two copies of that group, one for the row permutations and one for the column permutations.
