To make a number negative press the button that looks like a :guilabel:`+/-`. To insert decimals press the decimal point button which looks like a :guilabel:`.` when you get to the part which is less than a whole number. To clear input from Kcalc Press the button with a :guilabel:`C` on it. To group operations so they happen together use the parenthesis to make things grouped together for example 2*(2+3) would give the result of 10 because it would add 2 and 3 and then multiply by two.
