What is TR (915)- TR (895)=
tangare [24]

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).
