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

If you want even more functionality of Kcalc there is also scientific mode which is acessed from :menuselection:`settings --> scientific mode` radio button. The button 1/x takes takes 1 and divides it by the number currently on the calculator also known as taking the reciprocal. x! read x factorial will take the number X you entered and multiple each number going down to 1 for example 5! would multiply 5*4*3*2*1.

The x squared button will take a x*x and multiply it by itself. The button with x and a superscript y will take x the number you have in will exponeniate x to the power of y. The x 10 with a supercript y will end up multiplying x by 10 to the power of y so for example to multiply 5 by 10 to the power of 3 entering in will give the answer of 5,000.
