[ASSIGNMENT] ⭐÷÷÷÷÷÷÷Challenge÷÷÷÷÷÷÷÷÷⭐ 👉✍calculator without any operator✍👈. ( OVER)

Question

my first challenge
description

make a calculator without any operator
for addition and subtraction, it's easy
but in multiplication it will also multiply decimal number like ( 65*5.7) and negative numbers also like (-32*46)
and for division like (21/3) &(3/43)&(53/43)

WITHOUT ANY USE OF THIS + - * / and ++ , --

basically i want to know core of coding

how operator (which i think it's function) works

hence the result is
