To adjust the speed of slide transition for your lessons in Little Math, simply follow the steps below:

1. Launch Little Math.

2. Click on the Playback button at the top of Little Math.

3. Select the lesson in which you would like to change the speed of its slide transition.

4. Click on the Auto Forward button on the bottom right of Little Math to enable the Auto Forward setting, which allows you to play back presentations continuously, without needing to click a mouse button or press the spacebar to proceed to the next slide.

6. The Auto Forward Settings window will show up. You can adjust the duration of each slide by adjusting Auto forward delay and Delay between equations.

Delay between equations - Change how much longer Little Math will wait after the end of the current equation before playing back the next equation.

Auto forward delay - Change how much longer Little Math will wait after the end of the current slides' completion before playing back the next slide.

Using Auto forward delay in combination of Delay between equations can further increase or decrease the speed for your lessons in Little Math.

7. If you want to apply the same Auto Forward settings for all lessons, click on the Override button on the bottom left of Little Math to enable the Override setting.

8. Click on the cog button next to the Override button.
