I have to write a program which asks for three different numbers that then shows the three numbers that i wrote and then adds the biggest and the smallest number that i wrote.
Example:
Write your first number: 5
Write your second number: 4
Write your third number: 8
Sum is: 12
So far I've written a program that asks for three different numbers, it looks like this:
x=input('Write your first number: ')
y=input('Write your second number: ')
z=input('Write your third number: ')
That's everything that i have written so far. I'm thinking that i would need to write some 'elses' and 'if's' which commands which of x,y,z is the largest and the smallest.
Thanks!

it's probably easier if you store the values in one variable, that way you do not need any if-else commands
x = zeros(3,1);
x(1)=input('Write your first number: ') ;
x(2)=input('Write your second number: ') ;
x(3)=input('Write your third number: ')
sprintf('Sum is: %1.0f', min(x) + max(x))

Can you use sort()?

Hint. Try this:
if x > y && x > z
theMax = x;
elseif y > x && y > z
theMax = y
and so on. Obviously use < instead of > when you want to find the min.
