clear;
money_borrowed= 1000
m = money_borrowed
annual_interest= 10/100
a = annual_interest
time_passed_for_payment_in_year= 2
t = time_passed_for_payment_in_year
debt= m * (1+ a/12)^(12*t)
s=vpa(debt)

Ran in:
format bank
Q = @(v) sym(v); %convert number to symbolic number
money_borrowed = Q(1000)
money_borrowed = 
1000
m = money_borrowed
m = 
1000
annual_interest= Q(10)/100
annual_interest = 
a = annual_interest
a = 
time_passed_for_payment_in_year = Q(2)
time_passed_for_payment_in_year = 
2
t = time_passed_for_payment_in_year
t = 
2
debt= m * (1+ a/12)^(12*t)
debt = 
s = double(debt);
s
s =
