Whilst Soulver happily accepts words and sentences alongside numbers, there are some expressions which cannot be evaluated.
Here are some examples of problematic expressions:
Anything divided by zero is impossible to calculate.
Example:
1/0
Decimals with more than one dot will not evaluate.
Example:
1.1.3 + 1.2.1
Absurdly large numbers may not be evaluated.
Example:
123^123123123
You can not add units of different types together.
Example:
10 meters + 3 hours
Soulver will not allow you to redefine a variable in terms of itself.
Example:
a = 2
a = a + 21
You cannot use the alphabetical letter "x" as a times operator. Use * instead (and by default it will be replaced with the subtlety different (×) character
Example:
5 x 4
If your expression still does not evaluate, there may be a bug. Please email us with a description of your problem.
