subtraction and division, in that order
subtraction and multiplication, in that order

Answer 1

If we take the amount of points to be x before doing any operations on it ,
george has 2 times points of x
however x is 4 points less than sisters points which is 16 points
Then we subtract 4 from 16 = 12
12 is equal to x and george has twice of x
Therefore we first subtract 4 from 16 and then multiply it by 2, thats 12*2 = 24
therefore george has 24 points
the operations are subtraction and multiplication in order
