Wonderfull community here. I Searched this forum and can’t locate a solution. I am trying to create an expression that will calculate three variables within a set equation.
example:
“enter first number in text block”
“enter second number in text block”
“enter third number in text block”
“press calculate button”
(formula): num1 * num2 * num3 * 0.8 / 27 * 1.15 = label text box answer
Create your formula with math block , depending on your need . Then as items between the operation you have to add the block textbox.text that got the text value inside the textbox.
When you click on the button you have also introduce an if then else control
If textbox.text 1 is empty or textboxe.text 2 is empty or textbox.text is empty then show a message “you have to fill all the textboxes” else add the operation block
If you don’t need the notification add only the math block
In settings about textbox in the design editor , you can set the value of the textbox and force them to get only number , so it will show only a number keyboard
As said @Still-learning you don’t need extensions for easy math expression. Be careful about position of the blocks and how they will be connected.
I think yuo know that [(3x4x5)/5]x6 is different to (3x4x5)/(5x6)
