PEDMAS says parentheses first       then Mult or Division    then  add or subtract

7+(10-4)2  / 4

7 + (6)2 /4

7 + 12/4

7 + 3

10

For this problem we can use pemdas to solve but please note you have an indicaion of multiplication at the end assuming you want this part answered only.... 

 

 

But any way using pemdas we can solve the following (It can also be said in an ancryom to help remeber Please excuse my dear anut sally

 

It stands for the following operations as well 

 

1.Exponets 

2. Parenthasess 

3. Mutiplication 

4. Division 

5.  Addition

6. Subtraction 

 

So to satrt you off on the right foot here's what you do 

 

 

7 + (10 − 4)2 ÷ 4 ×  (We first start off with Parenthasess because there are no exponets so we make sure we follow the order. 

 

7 + (6) (2) ÷ 4 x    (Now after we have simplified the parenthasess we have 6 but notice how it ends up next to two I have put them in parentasses in individual slots to indicate that they are to be multiplied because remeber numbers next to each other or with an x or a dot indicates multiplication 

 

7 + 12 ÷ 4 (now we have 12 ÷ 4 so that totals 3) 

 

7 + 3 = ? 

 

and now it is in the most simpliest forum so it means  

 

7 + 3 = 10  (And ten times what every you have is the answer.
