Calculate the value of the mathematical function y = f (x). It is possible to assign to x any integer, rational number, irrational number. For example, you can assign square root 2 to x. It is not necessary to fix it to decimal. The calculation result is output in the form of a fraction using square root. It is exactly the same as math calculations. You can also convert the result to decimal. Calculate the values of f (α) and f (β) for two kinds of values, x = α and x = β, and f (α) + f (β), f (α) - f ), F (α) * f (β), f (α) / f (β) can also be calculated.

Verdict
The clearest difference is in-app purchases: functionCalculator at none against Linear Equations Calculator's 8. functionCalculator also leads on rating (4.3 vs 4.1) and iOS requirement (10.3 vs 15.0). Linear Equations Calculator's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 11 months). On price and device support there is nothing between them.
