What's the best code for this equation: 
Such that all numbers turn into wild cards and x is positive or negative integer (no fractions or decimals)
Hello Ahmad,
For cases where x needs to be a mulitple of 0.5 (your previous discussion) or different from 0 (above), the problems may be doable with the Calculated question but they become cumbersome and difficult to do. Instead, consider using the Formulas question type or the STACK question type. With the Formulas question type, your problems can be done within minutes.
