simple interest:
1000 + (1000 * 0.1) * 2
compound interest:
1000 + 1000 * 0.1 + (1000 + 1000 * 0.1) * 0.1
or
1000 * (1 + 0.1) ^ 2
as function
simple interest:
function current = simple_interest(debt, rate, period)
current = debt + (debt * rate) * period;
end
compound interest:
function current = compound_interest(debt, rate, period)
current = debt * (1 + rate) ^ period;
end

I'm sorry. I'll be more careful from now on.

Compound the interest once a year:
debt = 1000 + 1000 * 0.1 + (1000 + 1000 * 0.1) * 0.1

(I moved the flag content to the answer body, since it shouldn't have been a tag)

p = 1000
r = 10/100
n= 1
t = 2
S =(1.1)^2
debt = p* S

The problem is simple and related to finance,
Borrowed_money = 1000;
Interest_rate = 10/100;
Delay_year = 2;
debt = Borrowed_money*(1+Interest_rate)^Delay_year
