Hi ! A 19 + 7 / 2 - 5 According to PEMDAS, division comes first, so we start by diving 7 by 2, which equals 3.5. 19 + 3.5 - 5 = 17.5
B 19 + 7 / 2 - 5 In order for this to equal 8, the brackets will be placed like this: (19 + 7)/2 - 5 It gives (26)/2 - 5 Then we divide 26 by 2 (according to PEMDAS once again) We get 13 - 5 = 8
C 19 + 7 / 2 x 6 + 1 In order to get 2 as an answer, we place the brackets this way: (19 + 7)/(2 x 6 + 1) (26)/(12 + 1) 26/13 = 2
