😀😀 Sure 😁

There's no priority when we solve addition and subtraction. its Same Value.
you can solve the problem one by one from the left. 

20-8+2+3=17

20-(8+2+3)=7

right answer is 17

Hello @Jelly Jenny, 


1) 3 + 3 + 3 =  9;
2) 3 + 3 + 5 = 11;
3) 8 + 8 + 5 = 21;
4) 20 + 20 + 20 = 60;
5) 20 - (8+2+3) = 7 is the final answer

There's no priority when we solve addition and subtraction
or  multiplication and division. 
Addition and subtraction are equal in value.
multiplication and division are equal in value.
in this case,
you can solve the problem one by one from the left. 

20-8+2+3=17  right answer is 17 with out Bracket

20-(8+2+3)=7  answer is 7  only with the Bracket 

10x4/2x10/4=50

10x4/{(2x10)/4}=8


+ and -   equal value
x and /    equal value
x,/,+,-  Multiplication and division are always priority over subtraction and addition.   

 ex)  2+4x2-10/2-2+2+2=7

Hi. I would like to change my answer from 17 to 7. Thank you to my daughter and @Pummy_Raj for a quick refresher course of Algebra! It has been over 30 years since I took Algebra and I apparently was a little rusty, Haha!
