Looking at this https://en.wikipedia.org/wiki/Apple_keyboards#Twentieth_Anniversary_Macintosh_Keyboard_(M3459) https://en.wikipedia.org/wiki/Apple_keyboards#Twentieth_Anni... I see models with a power button, clearly labeled with the ISO standard symbol for a power button, and models with no power button, because it moved back to the case (and used the ISO standard symbol on it). By the time I was 13 I had used mice on four different GUIs so I have trouble sympathizing with your difficulty. User interfaces aren't facts of nature, which is a great learning opportunity to have in school. But learning opportunities must be taken.

Apple didn't use the IEC power symbol on their keyboards until the iMac-- prior keyboards used a left-pointing triangle on the power button. But most of these machines shipped in an era where there wasn't necessarily any standardization of how to turn the machine on in the PC-compatible world either-- the now-standard momentary electronic switch on the front of the case came with the ATX spec in 1995. Before that, you'd usually have a flip switch or latching power button somewhere on the case. (Macs were unusual for the era in having power on the keyboard from the ADB keyboard on.)
