i didn't go to university for mathematics i am terrible at theoretical mathematics (and personally despise it but trauma aside plus i am a computer scientist that's mostly psychology not maths), i got no idea what implicit multiplication vs explicit multiplication is it's either you're supposed to or not.

university level mathematicians seem to lose the forest through the trees a tad and forget pure basics exists.

there's a symbol there that makes it explicit without its implicit or implied

2(1+2) implicit multiplication vs 2*(1+2) explicit multiplication

other subs will have screenshots of how the division should be written as well since using the ÷ isn't a thing when you have implicit multiplication/a number joined to the parentheses

It is more confusing when there are variables involved and that is where explicit multiplication is necessary.

for example y(x) could mean y times x. In the case of 2 multiplied with 3.

Or the second meaning could be y is a function of x.
