Use BEDMAS/PEMDAS.

All we are doing is applying BEDMAS/PEMDAS laws to this expression.

$15 div (~3) - (~2)+2.3(~2.1)$

BEDMAS says we do brackets first. Well the brackets are just terms so nothing we can do there.

There are no exponents so we do division/multiplication first.

We can divide the $15$ by $~3$ as well as multiply $2.3$ by $~2.1$ .

$=~5 - (~2)-4.83$

Now we just add/subtract the remaining terms.

$=~3-4.83$

$=~7.83$

There we go! If we evaluate the expression, we get $~7.83$ .

Hope this helps :)
