Quoting directly from their 1990 paper. The key observation is that multiplying two 2 × 2 matrices can be done with only 7 multiplications, instead of the usual 8 (at the expense of several additional addition and subtraction operations).

The coppersmith­winograd algorithm relies on a certain identity which we call the coppersmith­winograd identity. Strassen's algorithm, the original fast matrix multiplication (fmm) algorithm, has long fascinated computer scientists due to its startling property of reducing the number of computations required for multiplying n × n matrices from o ( n 3) to o ( n 2.807). 44th acm symposium on theory of computation,.
