ragscalculator2 : : macro name
(1st number) : first number of your math equation
(math operator) : the math operation you want preformed
for + : use "add"
for - : use "subtract"
for x : use "multiply"
for ÷ : use "divide"
(2nd number) : second number of your math equation
<<ragscalculator2 2 subtract 2>>
produces just the solution to the equation/a number
0
Can be expanded for more numbers/equation steps and using the other math filter operators Tiddlywiki provides (abs, add, ceil, divide, exponential, fixed, floor, max, maxall, min, minall, multiply, negate, precision, product, remainder, round, sign, subtract, sum, trunc, untrunc)
As with the calculator tiddler, the macro can be used with variables for input from other sources.

Mohammad,
Nice work! I shall be studying this, definitely something for your TWScripts-- feel free to borrow anything from mine (like the calculator graphic design) for yours : )

No worry at all, your ragsculator was added see

One thought. Is there a way that you could take the RESULT of a first operation and use that number for the INPUT number of a second step ... and so on?Hope this is clear!

As with the calculator tiddler, the macro can be used with variables for input from other sources.
<ragscalculator $(num1variable)$ $(operatorvariable)$ $(num2variable)$>> macro with values 32, 64 typed in:
<<ragscalculator2 32 add 64>>
= 96
values 32, 64 read from fields:
<$set name="n1var" value={{!!filter-field1}}>
<$set name="n2var" value={{!!filter-field2}}>
<<ragscalculator2 $(n1var)$ add $(n2var)$>>
</$set></$set>
96
macro in a list generating a table, reading values from fields:
<table>
<tr><th></th><th>field 1</th><th>field 2</th><th>macro output</th></tr>
<$list filter="[prefix[zz test pg]]">
<$set name="n1var" value={{!!filter-field1}}>
<$set name="n2var" value={{!!filter-field2}}>
<tr><td>{{!!title}}</td><td>{{!!filter-field1}}</td><td><$view field="filter-field2"/></td>
<td><<ragscalculator2 $(n1var)$ add $(n2var)$>></td></tr></$set></$set></$list></table>
| field 1 | field 2 | macro output | |
|---|---|---|---|
| zz test pg1 | 12 | 24 | 36 |
| zz test pg2 | 27 | 18 | 45 |
| zz test pg3 | 72 | 18 | 90 |
| zz test pg4 | 11 | 11 | |
| zz test pg5 | -5 | -25 | -30 |
| zz test pg6 | 12 | -12 | 0 |
To expand this for exponents, ie: 4 to the 4th power, a macro
<<tothepower basenumber multiply powernumber>>
could take "basenumber" (four) for both numbers in a multiply filter, save the result to a field/variable to insert into another multiply filter using the variable for both numbers of the filter, repeating "powernumber" number of steps.
