## How to use Math keyboard (calculator)?

The keyboard is simple to use. Tap to enter any sign and navigate through the problem with arrows in the top row.

Use new line ↵ button when you want to jump to the next row (for example, when entering systems of equations).

## Where are the solving steps?

## Where do I find more functions?

Advanced functions are grouped under the chips at the top of the Math keyboard.

Alternative functions can be input by holding any button with a small dot in the bottom right corner.

## Wrong result for trigonometric functions, why?

The standard use of the function cos is used as radians. Adding a degree symbol will give you the result you’re looking for:

Cos (30) - Radians

Cos (30°) - Degrees

You can find the degree symbol by tapping the trigonometry functions button (sin, cos, tan, cot) on the top left of the calculator keyboard.

Correct input: (-3)^2. Here the minus sign is "under " the square, you need to multiply negative 3 by itself and that is why the result is positive: (-3)^2= (-3)*(-3) = 9

Incorrect input: -3^2. In this case the minus sign is in front of the power, and therefore it is left out from the calculation, then you multiply two positive numbers and add a minus to the result: -3^2 = -(3)*(3) = -9
