Tired of juggling between Apple Notes and Calculator? A math feature in iOS 18 lets you solve equations instantly with just a quick settings tweak.

How to tweak math results in Apple Notes



If you're like most people, the Apple Notes app on your iPhone is a go-to for jotting down ideas, to-do lists, and even the occasional math equation. It's quick, convenient, and always just a tap away. But Notes can actually solve equations for you.

The new math result feature in iOS 18's Notes app transforms how you handle equations during note-taking. Instead of relying on a separate calculator or switching apps mid-task, Notes can now recognize, calculate, and display results directly in your document.

Math Notes seamlessly integrates math functionality whether you're a student solving quick problems, a professional calculating figures during a meeting, or someone organizing expenses. It's efficient and a handy alternative to a dedicated calculator for everyday math tasks.

How to change the Math Result options



Changing the Math Result options in the Notes app is quick and easy. It unlocks a smoother way to handle calculations directly in your notes. Instead of manually tapping the "=" sign, enable automatic result display in the Settings app.


  1. Open Apple Notes and either create a new note or open an existing one.

  2. Enter a mathematical equation, such as 5+3. The setting for math results will only appear after typing an equation.

  3. Tap the three-dot menu in the top-right corner of the toolbar to access additional options under Math Results.



The setting called Suggest Results means you have to press the space bar after the equation result appears to insert it into the note. The Insert Results option means the answer will be automatically inserted.

Math Results makes it easy to handle quick calculations without switching to the calculator. Enabling automatic math results in the Notes app transforms it into a versatile tool for quick and effortless calculations.

It helps you reduce unnecessary taps and save time, making the app even more convenient for everyday use. Math Notes ensure the Notes app stays ahead in assisting you with productivity and organization, whether for work, school, or personal projects.

    It would be useful to everybody, online press, users, and even Apple, to use the correct language.
    Notes do not solve equations, it computes expressions. 
    An equation is something like x^2-1= 0, and solving it means finding the values of the 'variables' that make the equality true.
    Computing an expression is executing a algorithm writter as a mathematicak expression: 3*5-2 means multiply 3 by 5, add 2 and tell us the results.
    The two things are wildly different, with different use cases, and very different complexity.

    Yes, I agree that would still be ‘compute’, but it is common even in math classes to say if a^2+b^3‎=?, and if a=3 and b=2, ‘solve’, or more commonly, ‘calculate’ the expression rather than compute the expression.  
    It’s technically better to say compute, although I prefer calculate. 
    Using the word “compute” was rare in my math background long ago. I got an 800 score in the SAT Advanced Math level II test, but that was 60 years ago. So I was pretty fussy about math terms too.  Has usage changed?  

    In 1960 through 1965, during my advanced H.S. math program, we didn’t have digital computers—they were in Universities with punch card input.  The term computer also described a person who specialized in solving advanced math problems and in high volumes. I think that’s a clue to older folks saying “solve the problem“—that’s what our teachers told us to do. So I think it comes down to expression vs equation. An equation equates two sides of the ‘equals’ sign. 

    Expressions and calculation results pasted from notes:  

    a=3, b=2

    a^2+b^3‎ = 17

    ———————————

    a=3, b=2, c=4

    3a^3 + 2b^2 +3c‎ = 101

    Another thought on this is that when you calculate the expression, you put an ‘equals’ sign and the result on the right. Ipso facto, you have an equation!

    Note: This is the first time I’ve typed an algebraic math problem in Apple Notes on an iPhone. I’m impressed with Math Notes. 

    I also wonder if a future version of Math Notes will have some abilities to solve equations.

    I just wish it had a Markdown mode so I could use it for technical notes.

    I may be using it wrong, but I have found dysfunctionality completely useless in notes. For example, it doesn’t recognise numbers written in a column with a line below it to do a sum. It also does not recognise divisions original as a fraction very often. 
    For example, if you write multiple calculations below each other, and want to do the sum of the results (so a basic table), it doesn’t recognise that, It is just too fickle.

    IThe term computer also described a person who specialized in solving advanced math problems and in high volumes.
    My understanding was the term computer referred to people who solved repetitive mathematical problems - not necessarily advanced math problems.  My memory tells me things like ballistics calculations...  but my memory is not what it once was (and was not that good then).
