1
Hold the Home button. It's the round button at the bottom of your iPhone, iPad, or iPod touch's casing.
- You may have to enter a passcode and tap the Home button to unlock your iOS device first.
- If you're using Siri on a Mac, click the multicolored icon in the top right corner of your screen.
- Siri is available on iPhones 4S and up, iPod Touch 5 and up, iPad 3 and up, and MacOS Sierra and up.

2
Tell Siri your equation. For example, if you want to solve 220 divided by 18, you would say "Solve two hundred twenty divided by eighteen."
- If you want to include a decimal point in your equation (e.g., "220.9"), you should say "point" (e.g., "two hundred twenty point nine").

4
Use Siri to solve advanced equations. For example, you can solve quadratic equations or factorials by telling Siri to solve for the base equation:
- For " $x^{2}+3x-4=0$ ", you would say "Solve X squared plus three X minus four equals zero."
- For " $8!$ ", you would say "Solve eight factorial."

Ask Siri other math-related questions. For example, you could say "How many prime numbers are between 1 and 100?"
- You could also ask Siri to calculate the tip for a meal by saying "What is a 20 percent tip on a $350 meal?"^{[1]

6
Ask Siri about equations you don't know. You might ask "How do you find the circumference of a circle?" to find out the equation used to measure circumference, for example.
- Asking about complex equations may lead Siri to link you to an online article about the subject.

Warnings

If you don't say "Solve" before stating an equation that starts with a variable (e.g., "Y"), Siri may hear "why" or another word instead.

Thanks!
