Andy_B Photographer Location United Kingdom London London  Quote from NATKINS I hear what you're saying, but apparently a basic calculator and Nokia are wrong too... cf. 'On my basic calculator, the answer is 9. On my Nokia phone in Portrait it is also 9' Oh well, there goes my education  good job I'm a photographer... Nick A calculator is just a tool, you have to know how to operate it. A basic calculator can only work with two numbers at once  if the calculation has more then it's your job to enter them in the right order. Saying the calculator is wrong is like blaming your car for being 'wrong' if you drive it the incorrect way up a one way street. It's not the car/calculator, it's the operator!!

stolenfaces Photographer Location United Kingdom London West London  Quote from hhoa 1 + 2 x 3 = 7 due to the order of operations in mathematics as i learnt at school. 1 + 2 x 3 should be the same as 1 + (2 x 3). Brackets should be unnecessary. It's not mathematics  it's arithmetic 

Like any dealer he was watching for the card that is so high and wild he'll never need to deal another...

Yup.... it's the operator. You should have entered the calculation into the calculator thus (to force it to do the multiplication first, as it doesn't know what's coming next): 2 x 3 + 1

mikethefoto Photographer This member has been suspended This member has been reset to pending Location United Kingdom Worcestershire  Quote from stolenfaces Clearly that's not true. Brackets clarify the expression, they are much more easily understood than the precedence of operators. In the real world the meaning of the expression would generally be clearer E.g I have one pound and can save 3 ponds a week so in two weeks time I will have 1 + (2x3) = £7 Or each week mum gives me £1 and dad gives me £2 so in 3 weeks I will have (1+2) x 3 = £9. In a month you will have enough ponds to make a lake!

StreetModel Photographer Location United Kingdom Essex Upminster / All UK  Quote from tonycsm Why not use Reverse Polish Notation  no parenthesis needed! Now THAT one you'll have to explain because I bet very few people have HP calculators...

tonycsm Photographer Location United Kingdom East Yorkshire Driffield  Quote from StreetModel Now THAT one you'll have to explain because I bet very few people have HP calculators... I'll leave you to look that one up as it takes a bit of explaining ... to be honest the last time I had anything to do with it was back in the 80's but it's a great concept if you're interested in mathematics! Here's a link that will explain it probably better than me... http://en.wikipedia.org/wiki/Reverse_Polish_notation
