Given Equation:-


\sf25 - 12 / [(8 - 5) * 1]


\\ \\

Step-by-step explanation:-


\\


\dashrightarrow \sf25 - 12 / [(8 - 5) * 1]

first write the equation so that you'll emit minor mistakes of writing wrong digits.


\\


\dashrightarrow \sf25 - 12 / [(3) * 1]

subtract 8 and 5 , which will give us result as 3


\\


\dashrightarrow \sf25 - 12 / [3 * 1]

open the brakets that contains 3.


\\


\dashrightarrow \sf25 - 12 / [3]

multiply 3 with 1 which will result 3.


\\


\dashrightarrow \sf25 - 12 / 3

open the brakets of 3.


\\


\dashrightarrow \sf25 - (12)/(3)

to make it easy to understand I have converted it into fraction form.


\\


\dashrightarrow \sf25 - (2 * 2 * 3)/(3)

simplify 12 which is contained in numerator.


\\


\dashrightarrow \sf25 - (2 * 2 * \cancel3)/(\cancel3)

as we can see after converting into fraction 3 is common both in numerator and denominator. So cancel ir.


\\


\dashrightarrow \sf25 - (2 * 2)

we no longer need the fraction as 3 is canceled.


\\


\dashrightarrow \sf25 -4

multiply 2 with 2 which will result 4.


\\


\dashrightarrow \bf21

finally after subtracting 25 and 4 , we got our answer as 21.
