If the estimated value is very different from the calculated value then the answer is wrong. Unfortunately, it does not work the other way. An estimate can be close to the calculated value but the answer can still be wrong.
The number 39 can be expressed as a multiplication problem using the factors 3 and 13, since (3 \times 13 = 39). Additionally, it can also be represented as (1 \times 39) or (39 \times 1). These factors demonstrate the different ways to compose the number 39 through multiplication.
How about 3*7*11 = 231 as a product of its prime factors
79 x 1 39.5 x 2
6x2x2
How about: 8*9 = 72
