The result is TR (20).
To determine the result of TR (915) - TR (895), the following logical-mathematical reasoning must be made:
We find a constant that is repeated in both values, which is TR.
In turn, both values have a different quantity, which multiplies that constant.
Therefore, you must perform this multiplication and then subtract the results, to obtain the final result.
- TR (915) - TR (895) = X
- 915TR - 895TR = X
- 20TR = X
Therefore, the result is TR (20).
