+118608 Oh I see the problem - I am glad that you have been persistant :)
this problems is
20÷2(5+5)
$$=20\div2\times(5+5)$$
parentheses first
$$=20\div2\times10$$
Now, division and multiplication are equally important. The division comes first so you do it first.
$$=10\times10$$
now multiply
$$=100$$
Yes. If you add 5+5 first, and then multiply by 2, don't you get 20?
My calculator gives me 1 when I ener this directly. What gives?
