That feeling when in the last page where they're doing the math question, it's actually wrong. 10+5*2 does not equal 16. Because the order of the question goes multiplication or division first and then the addition and subtraction. Thus meaning it become 10 + (5*2) = 10 + 10 = 20, I have no idea where they got it to 10 + (5-2) * 2, where did they get the subtraction to the 5?
