Question

Mmkay..
So...
On 2, I did the first step, now what do I do next??

Answer 1

notice that the 16 times 4 dissapeared
therefor 16*4=blank=64

the blank is 64


next line
89-64 dissaperaed
89-64=25
blank is 25

last is 25+12=37



blanks (including the 16) are
16
64
25
37

Answer 2

89 - 16 x 4 + 12

89 - 64 + 12

25 + 12

37
