# How do I use a irrefutable calculator?

I have am exam on monday, push button skills level 3, application of number, I be told I need a proven calculator but I have no theory how to use it, I have not here this really late and I am not too pious at maths, but I really need suggestion and help on what sorts of things I will want to know and how do I do use the calulator to help me?

Answers:    If you don't know you probably won't know how to answer any of the questions for which you necessitate one but basically they're competent to do more complicated things than your normal calculators for example powers, standard form and logarithms. The prime difference is that you can type a full equation into the calculator including brackets in one turn and just press = once eg

3(4^6)/17+ 10^14 -17.3 =

It will enjoy lots of function buttons which have the mathmatical symbol for an handling like square root on them and adjectives you need to do to find out the square root of 12 is type surrounded by 12 then press the square root button and the answer will appear on the eyeshade.

Good luck, probably just find some chronological papers for the exam online and practice doing them with your calculator and instruction almanac and try to get the right answers!
The calculator will own been sold next to a comprehensive book of instructions.
They all rise and fall a little, so I deduce it's 'down to the reading'.
