Store a value after doing a calculation on the original?

[josh48]

How do I store the value after the orginal value has been calculated.

For example I minus 10 from 100, and I want 90 to be stored and in the next calculation another 10 wil be minued from 90 not the 100 which the original.

in variables you can store these values

program sablon;
uses crt;
var a,b,c,d,e,f,g:integer;
begin
     clrscr;
     a:=10;
     b:=100;
     c:=b-a; {90}
     d:=c-a; {80}
     e:=d-a; {70}
     f:=e-a; {60}
     g:=f-a; {50}
     readln;
end.
