Love when my lecturer doesnt explain why he changed the 16 into 4x4. 🤯🤯🤯

Like I get that 4x4 is 16, but he just did it without explanation. Now I'll have to go in and get him to explain it to me in person cause I missed the lecture and couldn't ask live. 🤯🤯🤯
CONFUSED. If anyone knows please do explain it to my idiotic self. This class has me second guessing myself and it was just meant to be a revision class of highschool maths HAHAHAH. 😐

He explained it on the board

@MrAboo he didn't explain it with talking, he just wrote it out. I don't get it if he just write it like that without saying why he's crossing it out.

@SeductiveCactus he was canceling two 4’s he broke 16 down so he could do so. You just need to look at the work he showed, it explains your question on its own.

@MrAboo thanks for that. But obviously I didn't understand so I asked. Better to ask than not. It may seem obvious to you but it wasn't so much for me. 😊

@SeductiveCactus that’s ok there was a time I would have had to ask too. Nothing wrong with asking
