Let's look at some simple questions: Question 1: James can make $200 per day, what would be his annual income ( He works 5 days a week, 48 weeks per year) ? This is easy, just enter an expression as this in Xmart Calculator: 200 x 5 x 48 Question 2: How many times of tapping a button to calculate his annual income? 8 times on a normal calculator, 7 times on Xmart Calculator (you don't need to tap the '=' button). Question 3: What if his day rate is $320, $400, $500...? Well, very similar: 320 x 5 x 48; 400 x 5 x 48; 500 x 5 x 48... What's the problem? With a normal calculator, we have to enter the same buttons 'x 5 x 48' very time when the only value changes is just the day rate. Is there any way to just enter the day rate and the result will update automatically? With Xmart Calculator, YES! You can define a Algebra function like this: "IncomeByDay(X) = X x 5 x 48" Then you can just select the function and enter the value for 'X' and the result will update straight away! To get James annual income, you just need to tap buttons 4 times. -- End of questions -- Xmart Calculator is appreciated as an intelligent, programmable and expandable calculator based on text expression.
