Question

3+4(10-8)? I have to simplify

Answer 1

Hi so you start with PEMDAS wich means parenthesis exponents multiply divide add and subtract so that's the order. 
so we start with the order so its parenthesis so 10 minus 8 is to and are the question now looks like this: 3 + 4 2 
Now when are two numbers together and they don't have a sign we multiplied together.
it looks like 3+4x2
Now we multiply because we follow the rule.
now it looks like this: 3+8
Now 3 plus 8 is 11 so your answer is 11
Hope I had helped.
