the difference in implicit vs explicit? It’s the same operation

"implicit multiplication" isn't even a real thing in Maths, and isn't even multiplication to begin with - people use that umbrella term to either mean The Distributive Law - which is the first step is solving Brackets - or Terms, which are products, which is the result of a multiplication.

e.g. if a=2 and b=3, then...

axb=2x3 - 2 terms

ab=6 - 1 term

Multiplication comes first, then division

They can be done in either order, or even together, as long as you go left to right.
